Griffith failure criterion
Griffith failure criterion The two-dimensional relationship between shear stress and normal stress at the point of failure. The mechanism of failure is based on the formation, propagation, and joining of microscopic ‘Griffith cracks’ whose leading edges concentrate stress. Failure occurs when a critical stress is reached and the cracks propagate fully.
