二维有限域上裂纹与夹杂问题的边界积分方程方法

The Boundary Integral Equation Method for a Bounded Elastic Body Containing a Crack and an Inclusion

本文推导了任意形状边界有限域上裂纹与夹杂问题的积分方程,求得了以裂纹面上位错密度函数和夹杂上剪应力差表示的弹性力学基本解,给出了裂纹和夹杂尖端附近的应力强度因子表达式.

In this paper the boundary integral equation method is used to study abounded elastic body containing a crack and an inclusion.Here the fundamental solu-tions are expressed by dislocation density on crack and the difference of shear stress oninclusion.The stress intensity factors at the tip of crack and at the end of inclusion arealso given.
