| 摘 要： | 采用能量差率方法，首次导出了含偏轴裂纹三维有限大体剪切型应力强度因子封闭解，根据此方法，可充分利用二维结果解决三维问题，由此所得的解答退化到对称情况时与现有结果符合得很好。同时本方法的计算效率很高。

| Abstract: | Energy difference rate method is applied to establish a closed form solution about stress intensity factors of shear modes for three dimensional finite bodies containing inclined embedded cracks.Accordding to energy difference rate method,two dimensional results of stress intensity factor can be utilized sufficiently to solve the three dimensional problems of stress intensity factor.The results given by this method agree with the generally recognized ones satisfactorily when the cases degenerate into symmetric ones.Furthermore,systematical results of three dimensional stressintensity factors of shear modes can be obtained by energy difference rate method with high computational efficiency. |
