| 摘 要： | 扩展有限元法(XFEM)是一种模拟结构裂纹扩展的有效方法,它保留了有限元方法的许多优点,同时又克服了有限元法的一些缺陷,使裂纹扩展不再局限于单元边界。通过扩展有限元法模拟裂纹在构件中的扩展,分析工程结构构件中孔隙对裂纹扩展路径的影响,研究构件中孔隙对裂纹扩展的影响。

| Abstract: | The extended finite element method(XFEM)is an effective method to simulate structural crack propagation.It retains many advantages of the finite element method and overcomes some defects of the finite element method,so that the crack propagation is no longer limited to the element boundary.Through the extended finite element method to simulate the crack propagation in the member,the influence of the pores in the engineering structural member on the crack propagation path is analyzed,and the influence of the pores in the member on the crack propagation is studied. |
