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。
