摘　　要：本文研究了裂纹尖端位于各向同性材料及正交异性材料两相介质界面并且裂纹位于各向同性材料内Ⅰ型裂纹平面应变问题的塑性应力场．将各向同性材料及正变异性材料分别视为满足Ｍｉｓｅｓ屈服准则及Ｈｉｌｌ屈服准则的理想塑性材料，得到了裂纹尖端塑性应力场．In this paper, it is analyzed the plastic stress field of the plane-strain crack-tip of mode I which intersects perpendicularly to the interface of two phase of media (isotropic and orthotropic materials) and is in the isotropic material. both of the isotropic and orthotropic materials are regarded as perfect-plastic and each of them satisfies the Mises criterion Hill criteri criterion, the plastic stress field at the crack-tip is gained.
