| Abstract: | 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. \ \ |
