摘要
描述了两种基于有限单元计算面形裂纹应力强度因子的方法，建议了一种创造三维有限单元网格的途径。计算方法的精度通过和其它解析解或数值解的比较得到了说明。
Two finite element based methods are described in this paper for the calculation of stress intensity factors for planar cracks,and a proposal is made for efficient creation of three dimensional finite element models.The accuracy of the calculation method is demonstracted by comparison with other analytical or numerical solutions available in the literature. \ \
