摘要
本文采用Shmuely的有限差分格式，利用J积分计算了平面应变清形下纯Ⅱ型裂纹的动态起始问题的应力强度因子，并分析了它们随各种参数的变化规律，得出了一些有意义的结果。
It this paper, by using the finite difference scheme of Shmuely and the J integral,the dynamic stress intensily factors of the dynamic initial problems of Mode Ⅱ dynamic crack under the plate strain are calculated, their various regular patterns with different parameters are analyzed, and some useful results are obtained.
