Abstract

The extended finite element method (XFEM) is a newly developed method for studying the fracture problems. With the XFEM, the crack is independent of the grids. Compared with the traditional finite element method, it avoids dividing the complex mesh near the crack tip and remeshing work when simulating crack propagation. Thus the calculation efficiency of the XFEM is high. In this paper, a solid rocket motor grain with initial crack under an internal pressure was studied by the XFEM. The characteristics of crack propagation was analyzed and some meaningful conclusions were drawn.
