【摘要】 本文对于含有圆盘状共面裂纹群的无限体提出了一种计算方法.基本思想是首先利用圆盘状单裂纹之解以及局部坐标展开法将裂纹群问题化为求解一组线代数方程.通过求解此线代数方程组,最后获得圆盘状共面裂纹群之解.文中的计算实例表明这一方法是有效的.本文结果扩充了“应力强度因子手册”的内容.更多还原

【Abstract】 In this paper, a computational method for coplanar disk-shaped cracks within an elastic infinite body is presented. The basic idea is to use the single crack solution and the expansions of the local coordinates to reduce the complicated problem into a set of linear algebraic equations. By solving this set of linear algebraic equations, we could obtain the solution of multi-cracks problem finally. Numerical examples for 2, 3, 4 cracks show that the method presented here is quite workable. Eesultg contained in this paper extend the content of "Handbook of Stress-Intensity Factors" by G. C.
