摘要:

本文从广义米赛斯准则出发,利用裂纹尖端附近奇异应力场,得出了动态广义塑性区尺寸因子断裂判据,为解决动态裂纹的扩展,提供了依据。

Abstract: Based on a generalized Von Mises Criterion for yield and fracture, a fracture criterion of dynamic generalized plastic zone size factor is obtained by using a singular stress field near a crack tip. This makes it possible to solve the problems of the dynamic crack extension.
