摘要
本文对两种硬化指数的弹塑性材料界面裂纹尖端场进行了分析。通过对渐近场的计算,讨论了尖端场位移匹配问题和一阶静水应力场的存在,使应力解更加完备。
A detailed analysis of elasto-plastic interfacial crack-tip fields is given in this paper. From the calculation of asymptotic fields, different ways of displacement fields match caused by different pairs of material hardening exponents are obtained. The existance of a first-order hydrostatic stress field under crack face frictionlesss contact condition is indicated and the stress asymptotic expansion is thus more completed.
