基于裂纹表面位移间断的计算结果得到了裂纹前沿的应力强度因子。
So the stress intensity factors can be obtained by the displacement discontinuities.
还着重研究了在有限大体中，平行于裂纹边界尺寸对裂纹前沿应力强度因子的影响，及棱角缺陷的半径对裂纹体应力强度因子的影响。
The numerical results show that the effect of quarter spherical defect to stress intensity factor in the finite body is the same as that in the infinite body.
