摘要 介绍XFEM的基本理论,针对常规有限元计算困难的三维裂纹,运用XFEM完成三维高压管道中的裂纹扩展计算.根据管道裂纹扩展的计算结果,总结得到管道裂纹扩展的规律,得到径向裂纹比轴向裂纹更严重的结论. 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.
