利用伪力 位错法对各向异性复合材料中界面裂纹与界面下平行于界面的微裂纹的干涉问题进行了研究 ,推导出了界面裂纹及界面下裂纹的基本解 ,将裂纹间的干涉问题化为一奇异积分方程组 ,并借助Chebyshev多项式及Chebyshev数值积分法进行了求解 .在此基础上 ,针对几种典型的各向异性双材料结构进行了计算 .分析数值结果发现 ,材料失配对裂纹间的干涉有很大的影响 ,并且发现在纯I型荷载作用下 ,模型I的应力强度因子在能量释放率中起主导作用 . The interference of interfacial cracks in anisotropic composite materials with microcracks parallel to the interface at the interface was studied by pseudo-dislocation method. The basic solutions of interfacial cracks and interfacial cracks were deduced. The interfacial interference between the cracks Into a system of singular integral equations, and solved by Chebyshev polynomials and Chebyshev numerical integration method.On this basis, several typical anisotropic two-material structures were calculated.The numerical results show that the material mismatch on the crack And it is found that the stress intensity factor of model I plays a leading role in the energy release rate under pure type I load.
