摘要：
This paper presents an elastostatic crack analysis in three-dimensional (3D), isotropic, functionally graded and linear elastic solids. A boundary element method (BEM) based on boundary-domain integral equations is applied. A multi-domain technique and discontinuous elements at the crack-front are adopted. To show the effects of the materials gradients on the crack-opening-displacements (CODs) and the stress intensity factors (SIFs), numerical results for a penny-shaped crack are presented and discussed.
