| 摘 要： | 基于Dragon等人的准脆性材料的各向异性损伤模型，在平面应变条件下，考虑了裂纹面之间摩擦滑动的影响，建立了一种较简单的摩擦诱导的塑性理论，通过算例讨论了摩擦对于材料损伤行为的影响。计算结果表明，在某些加载路径下，摩擦造成的应力下降不可忽视。

| Abstract: | Based on the anisotropic damage model proposed by Dragon,et al for quasi-brittle solids under plane strain,a simple theory of friction induced plasticity is proposed by considering the effect of slide caused by friction in micro-cracks. The effect of friction on damage behavior of material is studied and the calculated results show that the stress decrement caused by friction can not be neglected in some loading paths. |
