| 摘 要： | 应用复变函数的方法,对于各向异性平面内存在一个穿透直线裂纹的情况,给出了在裂纹外作用任意集中力和集中力偶时的复Green应力函数,即应力函数基本解.通过基本解的叠加,得到了在几种常见面内力系作用下各向异性平面内裂纹的应力强度因子计算式.其计算方法简便,具有一定的工程实用价值.

| Abstract: | A fundamental solution of Green's stress functions caused by a concentrated force and moment acting on an arbitrary point in an anisotropic plane with cracks was derived with the complex variable function method. The expressions of stress intensity factors for a series of in-plane loading conditions were obtained with the superposition principle. The calculation was simple and useful in engineering. |
