| 动用复变函数及积分方法方法求解了反平面圆形夹杂和多圆孔多裂纹相互作用问题。为解决该问题，建立了两种类型的基本解。利用叠加原理和所得的基本解没圆孔和裂纹表面取待定的基本解密度函数，可得一组Ｆｒｅｄｈｏｌｍ积分方程，通过积分方程组的数值求解，可以得到密度函数的离散值，进而得到应力强度因子。 |
| 英文摘要: |
| By using of complex variable function and integral equation method, the interaction between antiplane circular inclusion and multiple holes and multiple cracks is considered in this paper. In order to solve the proposed problem, two kinds of elementary solution are presented. Utilizing the proposed elementary solutions and taking density functions of elementary solutions along holes' and cracks' surface as undetermined functions, a group of Fredholm integral equations can be established. After the numerical solution of the integral equations, the SIF values at the cracks' tips can be calculated. |
