WebGriffith's criterion can be used to estimate the critical failure stress for a given crack length. Let's calculate the critical stress of a typical glass pane when a 1" (25.4 mm) crack is … WebGriffith’s energy criterion for fracture. For a “perfectly brittle” material with a surface energy density , a necessary condition for crack initiation and growth is: γ G ≥2γ. Griffith proposed that fracture would occur when the energy release rate G attains the critical value, Gc =2γ. Thus the criterion for fracture initiation in a ...
