裂纹尖端弹塑性分析方法探讨

A Probe Into the Method of Analysis of the Elastic - Plastic Strain Near a Crack Tip

根据HRR理论以及薛大为提出的简化理论,给出了一种对平面应变Ⅰ型裂纹尖端进行弹塑性分析的方法,并根据此法得出了完全近似解。

According to the HRR theory and the simplified theory put forward by Dahwei Hsueh, a method of analysis of the elastic - plastic strain near the tip of a crack under plan strain deformation is presented in this paper . A complet solution is thus obtained through the use of this method .
