Abstract:The basic theory of XFEM is introduced. As to the problem that it is difficult to calculate 3D crack by the normal finite element, XFEM is used to perform the crack propagation calculation on a 3D high pressure pipe. According to the crack propagation calculation results of the pipe, the law of pipe crack propagation is summarized and it is concluded that the crack in radial direction is more critical than that in axial direction.
