Study of numerical problem based on the extended finite element method
ADVANCED MANUFACTURING TECHNOLOGY, PTS 1-4(2012)
摘要
The extended finite element method (XFEM) provides an effective tool for analyzing crack problems. The control equations and the weak form can be established through balance equations,boundary condition, geometry equations,etc. After the establishment of stiffness matrix,the crack problems can be solved by XFEM conveniently.
