摘要
本文使用边界积分方程方法，将非对称载荷作用下的平面裂纹问题，归结为求解一组混和型奇异积分方程，并构造了高精度的数值方法，为说明本文的可靠性，文中对几个实例作了数值计算，得到了它们的应力强度因子。
In this paper,by use of the boundary integral equation method,finite plane crack problem under asymmetric loadings is reduced to solving a set of mixed-type integral equations.The High precision numerical method is also given.To show its reliability and application,we calculated several examples which are useful in engineering practice and obtained their stress intensity factors.
