New Method for Studying the Strength of Brittle Bodies with Cracks

摘要

The problem of tension of a plate made of a brittle material with a central through crack is considered. The traditional approach to solving the problem of strength of brittle bodies, which is based on linear fracture mechanics, is discussed. The apparatus of a generalized theory of elasticity, which is based on analyzing the state of stress in a medium element having small but finite sizes, is used to solve the problem of crack.
