Griffith's criterion
Griffith's criterion Fracture mechanics was developed during World War I by English aeronautical engineer A. A. Griffith – thus the term Griffith crack – to explain the failure of brittle materials. Griffith's work was motivated by two contradictory facts: The stress needed to fracture bulk glass is … See more Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials.

WebThe crack-extension criteria of Griffith and Barenblatt take account of the cohesive forces in rather different ways, but are both of the same form. Therefore, if they are to agree, the surface energy T appearing in the Griffith criterion must be related in a definite way to Barenblatt's modulus of cohesion K.
