Abstract:
The tensile strength of a material for a given flaw size can be determined from its fracture toughness, Gc. Griffith's criterion for unstable crack propagation in brittle materials defines Gc as the critical rate of release of elastic energy (with respect to crack length) at which the crack become unstable.
