| 摘 要： | 对于面两侧为具有不同屈服强度的理想弹塑性材料，本文给出在平面应变条件下静止界面裂纹尖端应力场的构造。讨论了同一介质内部以及界面两侧的连续条件。在一定条件下，给出应力单参数渐近场解。应力的分布依赖于材料常数Ｅ１，Ｅ２以及材料参数ｍ（ｍ＝Ｋ１／Ｋ２，为屈服强度比）①．关键词：

| Abstract: | he construction of the crack near-tip field at the interface in an elastlc-perfectly-plastic bimaterial is studied for the station case under the condition of the plane strain.The basic solution and continuity condition of the self-similar fields are given.The asymptotic near-tip field with single parameter is obtained.The distribution of stresses is greatly in fluenued by the interface material parameter m(m=K1/K2) |
