| 摘 要： | 应用复变函数Cauchy积分的方法,对含有椭圆孔或裂纹的各向异性平面,系统地导出了当其在面内受任意集中载荷作用时的复应力函数解或裂纹应力强度因子解析解,即基本解;并通过基本解的迭加,得到了在椭圆孔周或裂纹表面作用一般外载时的解,其特例证实了上述解的正确性。

| Abstract: | Using the Cauchy Integral Method of a complex variable, fundamental solution of the complex function or the stress intensity caused from a concentrated load acting on an arbitrary point in an anisotropic plane with an elliptical hole or a crack is systematically derived. By the superposition of the fundamental solution, the solutions for the case of general loads applying on the boundary of the elliptical hole or the face of the crack are obtained and proved to be right according to some particular examples in this paper. |
