The extended finite element method (X-FEM) can model arbitrary cracks independently of the finite element mesh. Therefore, X-FEM can be used to efficiently perform stress analyses in the field of fracture mechanics. This paper describes the application of X-FEM to stress analyses and crack propagation analysis. As numerical example, the problem of a three-dimensional body with a planar crack is solved and the distribution of energy release rate is evaluated. The obtained results are verified by comparing with those obtained using conventional finite element analysis. Moreover, the crack propagation analysis is performed by X-FEM in conjunction with the fatigue crack propagation law, which gives the relation between the energy release rate and the crack extension length.
