Abstract

The critical coefficient of stress intensity in linear fracture mechanics and an analytical expression for evaluating it have been established for the conditions of absolutely brittle fracture in a continuous isotropic medium. At the same time, the resource of plasticity in actual discrete (crystalline) materials is often determined using the concept of fracture toughness (crack resistance) calculated by the same equation as that used for evaluating the critical stress intensity. The article concerns the causes and consequences of this phenomenon.
