摘要
涉及两相正交各向异性体界面下裂纹间干涉问题的研究 .多裂纹问题被分解为只含单裂纹的子问题 ,利用位错理论和裂面应力自由条件 ,列出一组可数值求解位错密度函数的奇异积分方程 ,从而求得应力强度因子 .
This paper deals with the interaction between subinterface cracks in biamaterial orthotropic materials. The original multiple cracks problem is decomposed into the subproblems containing only one crack. Introducing the complex potentials modeling dislocation singularity near the interface, a system of singular integral equations are derived from the traction free conditions on the crack faces. After determining the dislocation density functions, the stress intensity factors at the crack tips are given.
