==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

==List of British military alliances==&lt;br /&gt;
===Scottish military alliances===&lt;br /&gt;
{{main|Auld Alliance}} ([[1165]]-[[1560]])&lt;br /&gt;
&lt;br /&gt;
The Auld Alliance was a military alliance between the countries of [[France]], [[Norway]], and [[Scotland]]. Though Norway never invoked the treaty, the Scots and the French did. The treaty stated that if any of the three nations was to be attacked by a third party, that the other two nations that belonged to the treaty would invade the aggressor. The effects of this military alliance happened many times in history. In [[1336]], at the beginning of the Hundred Years&#039; War, the French king Philip VI provided military support for David II, who fled to France after being deposed by Edward III of England. The Auld Alliance can also be said to have inflamed the English invasion of Scotland, starting the [[Wars of Scottish Independence|First War of Scottish Independence]]. In [[1346]], under the terms of the Auld Alliance, Scotland invaded England in the interests of France. In [[1421]], at the Battle of Baugé, French and Scots forces dealt a crushing defeat to the English, for which the Scots were richly rewarded. In addition, in [[1429]] Scots came to the aid of Joan of Arc in her famous relief of Orléans; many went on to form the Garde Écossaise, the fiercely-loyal bodyguard of the French monarchy. Many Scottish mercenaries chose to settle in France, although they continued to consider themselves &amp;quot;Scots&amp;quot;. However, when Scotland considered itself Protestant by the [[Treaty of Edinburgh]], the treaty was considered void, since France was still Roman Catholic.&lt;br /&gt;
&lt;br /&gt;
===English military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1386]]-)&lt;br /&gt;
&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British [[Iberia]] [[Peninsular War]]. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the [[Azores]] were again offered to the British Royal Navy.&lt;br /&gt;
&lt;br /&gt;
* [[Catholic League (Italian)|Holy League]] ([[1510]] to [[1513]])&lt;br /&gt;
&lt;br /&gt;
The War of the League of Cambrai (1508–16), sometimes known as the War of the Holy League and by several other names, was a major conflict in the Italian Wars. The Kingdom of England participated in the alliance of the Holy League against France (1511–13). The Kingdom Scotland was part of the Franco-Venetian alliance (1513–16), while the Kingdom of England was against it.&lt;br /&gt;
&lt;br /&gt;
* [[Triple Alliance (1668)|Triple Alliance]] ([[1668]])&lt;br /&gt;
&lt;br /&gt;
The Triple Alliance of 1668 consisted of England, Sweden, and the Republic of the United Provinces (the Netherlands). It was formed to halt the expansion of Louis XIV&#039;s France in the War of Devolution.&lt;br /&gt;
&lt;br /&gt;
* [[Grand Alliance]] ([[1689]] - ?)&lt;br /&gt;
The Grand Alliance (known, prior to 1689, as the League of Augsburg) was a European coalition, consisting (at various times) of Austria, Bavaria, Brandenburg, England, the Holy Roman Empire, the Republic of the United Provinces (the Netherlands), the Palatinate of the Rhine, Portugal, Saxony, Spain and Sweden. The league was named the &#039;Grand Alliance&#039; after England had joined it. The primary reason for the League&#039;s creation was to defend the Palatinate from France. This organization fought the War of the Grand Alliance against France from 1688 to 1697.&lt;br /&gt;
&lt;br /&gt;
===British military alliances===&lt;br /&gt;
* [[Anglo-Portuguese alliance]] ([[1704]]-)&lt;br /&gt;
The Anglo-Portuguese, signed in 1373, Alliance between England (succeeded by the United Kingdom) and Portugal is the oldest alliance in the world which is still in force. Many times in history, this alliance has served England (and later Britain) because it was the stronger country, but also Portugal whenever it was the stronger country. This treaty largely influenced the British Iberia Peninsular War. The last time that this treaty effected British history was during the 1982 Falklands War the facilities of the Azores were again offered to the British Royal Navy.&lt;br /&gt;
* [[Triple Alliance (1717)]]&lt;br /&gt;
The Triple Alliance was an agreement between United Kingdom, France and the Republic of the United Provinces (the Netherlands), against Spain, to prevent Spain from becoming a superpower in Europe.&lt;br /&gt;
* [[Triple Alliance (1788)]]&lt;br /&gt;
The Triple Alliance of 1788 was an alliance between Great Britain, Prussia and the Republic of the United Provinces (the Netherlands) against France. The alliance was formed to keep France from becoming a superpower in Europe by taking over the Dutch colonies.&lt;br /&gt;
* [[Anglo-Japanese Alliance]] (1902)&lt;br /&gt;
The Anglo-Japanese Alliance was signed in London on January 30, 1902 by [[Lord Lansdowne]] (British foreign secretary) and [[Hayashi Tadasu]] (Japanese minister in London). The alliance was renewed and extended twice, in 1905 and 1911 before its demise in 1921. It officially terminated on August 17, 1923. This alliance helped the British contain Russia and helped Britain&#039;s navy by providing coaling stations and repair facilities.&lt;br /&gt;
* [[Entente Cordiale]] (1904)&lt;br /&gt;
The Entente Cordiale (French for &amp;quot;friendly understanding&amp;quot;) is a series of agreements signed on April 8, 1904, between the United Kingdom and France. It resolved differences concerning influence and control in various countries including Egypt, Morocco, Madagascar, Newfoundland, Siam (Thailand), West and Central Africa. The agreement also acknowledged the right of free passage through the Suez Canal. The year after its signing, Britain&#039;s sympathetic attitude toward France&#039;s position in Morocco helped to ward off a challenge from Germany to the status quo in the North African kingdom (the Tangier Crisis). The agreement also paved the way for the diplomatic and military cooperation that preceded World War I.&lt;br /&gt;
* [[Triple Entente]] (1908)&lt;br /&gt;
The Triple Entente was the alliance formed in 1907 between the United Kingdom, France and Russia after the signing of the Anglo-Russian Entente. France and Britain had already signed the Entente Cordiale in 1904, and France had signed the Franco-Russian Alliance in 1894. This alliance brought Britain into World War I.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;

In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components.

&lt;br /&gt;
== The Need for Fracture Mechanics ==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Strain Energy Release Rate, G ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (for [[plane stress]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (for [[plane strain]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(5)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property. The subscript I arises because of the different ways of loading a material to enable a crack to propagate. It refers to loading via Mode I - the most common form of loading:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I - Opening mode (a [[tensile stress]] normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II - Sliding mode (a [[shear stress]] acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III - Tearing mode (a [[shear stress]] acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (4) and (5) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. To get around this problem, it is possible to introduce a [[dimensionless numbers|non-dimensional unit]] Y, thus giving:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = Y \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(6)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where Y is given by:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = \sqrt{\sec\left(\frac{\pi a}{W}\right) }\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(7)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
for a sheet of finite width W containing a through-thickness crack of length 2a or:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = 1.12 - \frac{0.41}{\sqrt{\pi}}\frac{a}{W} + \frac{18.7}{\sqrt{\pi}}\left(\frac{a}{W}\right)^2 - ...\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(8)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
for a sheet of finite width W containing a through-thickness edge-crack of length a.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Short Summary ==&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure. Fracture mechanics as a subject for critical study has barely been around for a century and thus is relatively new. There is a high demand for engineers with fracture mechanics expertise - particularly in this day and age where engineering failure is considered &#039;shocking&#039; amongst the general public.&lt;br /&gt;

He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (for [[plane stress]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (for [[plane strain]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(5)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property. The subscript I arises because of the different ways of loading a material to enable a crack to propagate. It refers to loading via Mode I - the most common form of loading:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I - Opening mode (a [[tensile stress]] normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II - Sliding mode (a [[shear stress]] acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III - Tearing mode (a [[shear stress]] acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (4) and (5) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. To get around this problem, it is possible to introduce a [[dimensionless numbers|non-dimensional unit]] Y, thus giving:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = Y \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(6)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where Y is given by:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = \sqrt{sec(\frac{\pi a}{W})}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(7)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
for a sheet of finite width W containing a through-thickness crack of length 2a or:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = 1.12 - \frac{0.41}{\sqrt{\pi}}\frac{a}{W} + \frac{18.7}{\sqrt{\pi}}(\frac{a}{W})^2 - ...\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(8)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
for a sheet of finite width W containing a through-thickness edge-crack of length a.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Short Summary ==&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure. Fracture mechanics as a subject for critical study has barely been around for a century and thus is relatively new. There is a high demand for engineers with fracture mechanics expertise - particularly in this day and age where engineering failure is considered &#039;shocking&#039; amongst the general public.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;

An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;

&lt;br /&gt;
== The Need for Fracture Mechanics ==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;

If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;

== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (for [[plane stress]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (for [[plane strain]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(5)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property. The subscript I arises because of the different ways of loading a material to enable a crack to propagate. It refers to loading via Mode I - the most common form of loading:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I - Opening mode (a [[tensile stress]] normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II - Sliding mode (a [[shear stress]] acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III - Tearing mode (a [[shear stress]] acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (4) and (5) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. To get around this problem, it is possible to introduce a [[dimensionless numbers|non-dimensional unit]] Y, thus giving:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

== Short Summary ==&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure. Fracture mechanics as a subject for critical study has barely been around for a century and thus is relatively new. There is a high demand for engineers with fracture mechanics expertise - particularly in this day and age where engineering failure is considered &#039;shocking&#039; amongst the general public.&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== The Need for Fracture Mechanics ==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Stain Energy Release Rate, G ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Griffith&#039;s Crack Theory: Stain Energy Release Rate, G ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]].

&lt;div&gt;&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Griffith&#039;s Crack Theory: Stain Energy Release Rate, G ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (for [[plane stress]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (for [[plane strain]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(5)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property. The subscript I arises because of the different ways of loading a material to enable a crack to propagate. It refers to loading via Mode I - the most common form of loading:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I - Opening mode (a [[tensile stress]] normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II - Sliding mode (a [[shear stress]] acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III - Tearing mode (a [[shear stress]] acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (4) and (5) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. To get around this problem, it is possible to introduce a [[dimensionless numbers|non-dimensional unit]] Y, thus giving:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = Y \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(6)&lt;br /&gt;

&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Griffith&#039;s Crack Theory: Stain Energy Release Rate, G ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (for [[plane stress]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (for [[plane strain]])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(5)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property. The subscript I arises because of the different ways of loading a material to enable a crack to propagate:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I: Opening mode (a [[tensile stress]] normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II: Sliding mode (a [[shear stress]] acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III: Tearing mode (a [[shear stress]] acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (4) and (5) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. To get around this problem, it is possible to introduce a [[non-dimensional unit]] Y, thus giving:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = Y \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(6)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where Y is given by:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = \sqrt{sec(\frac{\pi a}{W})}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(7)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
for a sheet of finite width W containing a through-thickness crack of length 2a or:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = 1.12 - \frac{0.41}{\sqrt{\pi}}\frac{a}{W} + \frac{18.7}{\sqrt{\pi}}(\frac{a}{W})^2\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(8)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
for a sheet of finite width W containing a through-thickness edge-crack of length a.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Short Summary ==&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure.&lt;br /&gt;

== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (for [plane stress])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (for [plane strain])&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(5)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property. The subscript I arises because of the different ways of loading a material to enable a crack to propagate:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I: Opening mode (a tensile stress normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II: Sliding mode (a shear stress acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III: Tearing mode (a shear stress acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (4) and (5) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. To get around this problem, it is possible to introduce a non-dimensional unit Y, thus giving:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

== Short Summary ==&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Griffith&#039;s Crack Theory: Stain Energy Release Rate, G ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I: Opening mode (a tensile stress normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II: Sliding mode (a shear stress acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III: Tearing mode (a shear stress acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (4) and (5) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. To get around this problem, it is possible to introduce a non-dimensional unit Y, thus giving:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = Y \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(6)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where Y is given by:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = \sqrt{sec(\frac{\pi a}{W})}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(7)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
for a sheet of finite width W containing a through-thickness crack of length 2a or:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Y = 1.12 - \frac{0.41}{\sqrt{\pi}}\frac{a}{W} + \frac{18.7}{\sqrt{\pi}}(\frac{a}{W})^2\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(8)&lt;br /&gt;

&lt;div&gt;&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Griffith&#039;s Crack Theory: Stain Energy Release Rate, G ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
If G ≥ G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;, this is the criterion for which the crack will begin to propagate.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (Plane stress)&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (Plane strain)&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(5)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;.

== Griffith&#039;s Crack Theory: Stress Intensity Factor, K ==&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G.R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (Plane stress)&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (Plane strain)&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. Note that the expression for K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; in Eq (2) and (3) will be different for geometries other than the center cracked plate, as discussed in the article on [[stress intensity]]. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property. The subscript I arises because of the different ways of loading a material to enable a crack to propagate:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
There are three ways of applying a force to enable a crack to propagate:&amp;lt;br&amp;gt;&lt;br /&gt;
Mode I: Opening mode (a tensile stress normal to the plane of the crack)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode II: Sliding mode (a shear stress acting parallel to the plane of the crack and perpendicular to the crack front)&amp;lt;br&amp;gt;&lt;br /&gt;
Mode III: Tearing mode (a shear stress acting parallel to the plane of the crack and parallel to the crack front)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Short Summary ==&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure.&lt;br /&gt;

&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by leak before break. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Griffith&#039;s Crack Theory ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
For the simple case of a thin rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G = \frac{\pi \sigma^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G is the strain energy release rate, σ is the applied stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. The strain energy release rate can otherwise be understood as: &amp;lt;i&amp;gt;the rate at which energy is absorbed by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
However, we also have that:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the [[brittle fracture stress]], a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]]. This [[fracture energy]] can otherwise be understood as: &amp;lt;i&amp;gt;the rate of strain energy release by growth of the crack&amp;lt;i&amp;gt;.&lt;br /&gt;

== Short Summary ==&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure.&lt;br /&gt;

&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]). These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. In many cases, failure of engineering structures through fracture can be fatal. For instance, failure of pressure vessels due to crack propagation could cause an fatal explosion. If failure were ever to happen, we would rather it were by [[yield (engineering)|yield]] or by [[leak|leak before break]]. As a consequence, a material property, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. This is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
==Griffith&#039;s Crack Theory ==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy.&lt;br /&gt;
&lt;br /&gt;
For the simple case of a rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the brittle fracture stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]].&lt;br /&gt;

Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure.&lt;br /&gt;

&#039;&#039;&#039;Fracture mechanics&#039;&#039;&#039; is a method for predicting failure of a structure containing a crack. It uses methods of analytical [[Solid Mechanics]] to calculate the driving force on a crack and those of experimental [[Solid Mechanics]] to characterize the material&#039;s resistance to fracture.&lt;br /&gt;
&lt;br /&gt;
In modern [[Materials Science]], &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is an important tool in improving the mechanical performance of materials and components. It applies the [[physics]] of [[stress (physics)|stress]] and [[strain]], in particular the theories of [[elasticity]] and [[plasticity (physics)|plasticity]], to the microscopic [[crystallographic defect]]s found in real materials in order to predict the macroscopic mechanical failure of bodies.&lt;br /&gt;
&lt;br /&gt;
An excellent introduction to &#039;&#039;&#039;Fracture Mechanics&#039;&#039;&#039; is: Adrian Demaid &#039;&#039;Fail Safe&#039;&#039; Open University (2004).&lt;br /&gt;
&lt;br /&gt;
==The Need for Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Engineering structures often contain cracks - arising either during production or during serevice (e.g. from [[Fatigue (material)]]).  These cracks can lower the strength of the structure beyond that due to loss of load-bearing area. As a consequence, a material propety, above and beyond conventional strength, is needed to describe the fracture resistance of engineering materials. this is the reason for the need for fracture mechanics - the evaluation of the strength of cracked structures.&lt;br /&gt;
&lt;br /&gt;
==Fracture Mechanics==&lt;br /&gt;
&lt;br /&gt;
Fracture Mechanics was invented during World War I by English aeronautical engineer, [[A.A.Griffith]], to explain the failure of brittle materials. Griffith was faced with the problem that theoretical calculations showed that the stress at the tip of a sharp crack approaches infinity. Accordingly, any structure containing a crack should fail, no matter how small the crack or how light the load. To solve this dilemma, Griffith developed a thermodynamic approach. He assumed that growth of a crack requires creation of surface energy, which is supplied by the loss of strain energy accompanying the relaxation of local stresses as the crack advances. Failure occurs when the loss of strain energy is sufficient to provide the increase in surface energy. For the simple case of a rectangular plate with a crack perpendicular to the load Griffith’s theory becomes:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;G_c = \frac{\pi \sigma_f^2 a}{E}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(1)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where G&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the critical strain energy release rate (also [[fracture energy]]), σ&amp;lt;sub&amp;gt;f&amp;lt;sub&amp;gt; is the brittle fracture stress, a is half the crack length, and E is the [[Elastic modulus|Young’s modulus]].&lt;br /&gt;
&lt;br /&gt;
Griffith’s work was ignored for over twenty years until a group under [[G. R. Irwin]] at the U.S. Naval Research Laboratory took it up during World War II. Their problem was that naval materials, e.g. ship-plate steel, are not perfectly elastic but undergo [[plastic deformation]] at the tip of a crack.  Eventually a modification of Griffith’s theory emerged from this work; a term called [[stress intensity]] replaced strain energy release rate and a term called [[fracture toughness]] replaced surface energy. Both of these terms are simply related to the energy terms that Griffith used:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_I = \sigma \sqrt{\pi a}\,&amp;lt;/math&amp;gt;&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(2)&lt;br /&gt;
&lt;br /&gt;
and&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{E G_c}\,&amp;lt;/math&amp;gt; (Plane stress)&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(3)&lt;br /&gt;
:&amp;lt;math&amp;gt;K_c = \sqrt{\frac{E G_c}{1 - \nu^2}}\,&amp;lt;/math&amp;gt; (Plane strain)&amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp; &amp;amp;nbsp;(4)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
where K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; is the [[stress intensity]], K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; the [[fracture toughness]], and ν is [[Poisson ratio|Poisson’s ratio]]. Fracture occurs when K&amp;lt;sub&amp;gt;I&amp;lt;sub&amp;gt; ≥ K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt;. Note that the expression for K in Eq. (2) will be different for geometries other than the center cracked plate, as discussed in the article on [[Stress Intensity]]. For the special case of plane strain deformation, K&amp;lt;sub&amp;gt;c&amp;lt;sub&amp;gt; becomes K&amp;lt;sub&amp;gt;Ic&amp;lt;sub&amp;gt; and is considered a material property.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Arising from the manufacturing process, interior and surface flaws are found in all metal structures. Not all such flaws are unstable under service conditions. Fracture mechanics is the analysis of flaws to discover those that are safe (that is, do not grow) and those that are liable to propagate as cracks and so cause [[structural failure|failure]] of the flawed structure.&lt;br /&gt;
