摘要
本文利用能量释放率法,导出三维含裂纹有限大体剪切型应力强度因子的封闭解。这种方法非常节省机时,可获得大量K_Ⅱ和K_Ⅲ的有用结果,所得结果与现有少量结果基本吻合。
In this paper, a new analytical-engineering method of closed form solution for stress intensity factors of shear modes for 3-D finite bodies with cracks is derived by the time saving energy release rate method. Hence a complete series of useful results of stress intensity factors K_Ⅱ and K_Ⅲ can be obtained. And the results provided by this method are in good agreement with some obtained by other methods.
