摘　　要：采用 Muskhelishvili复变函数方法 ,研究两相材料中两根倾斜裂纹应力强度因子的相互影响 ,将问题归结为求解一组 Cauchy型奇异积分方程 ,对倾斜裂纹端点的应力强度因子作了数值求解 .结果表明 ,两相材料的材料常数。By using the Muskhelishvili complex methods, the issue of interaction between bimaterial incline cracks was reduced to solve the Cauchy singular integral equations, in which the unknown functions are the dislocation density functions. The equations of the stress intensity factors (SIF) were obtained and solved numerically. And the SIF is influenced greatly by the bimaterial's constants and the cracks'configuration.
