The method to get the constant coefficients of weight functions is also analyzed, which is based on the SIFs by finite element method.
并分析了待定权函数系数的求法，即结合有限元计算混合型裂缝应力强度因子方法求出待定的权函数系数，继而得到了矩阵型权函数。
When the distance between the tips of different cracks is short enough, the SIFs of remote tips are larger than the intimate tips', and …
当裂纹相邻端距离较小时，裂纹远离端的应力强度因子较相邻端的应力强度因子值要大，表明裂纹将在远离端首先发生开裂；
Under the conditions of limitation, not only known results can be obtained but also the solutions of the SIFs at the crack tip of a circular hole with two symmetrical cracks were found out.
在极限情形下，不仅可以还原为已有的结果，而且给出带双对称裂纹的圆形孔口在裂纹尖端的应力强度因子。
