Analysis of the Crack Propagation Based on Extended Finite Method

Abstract:

For solve efficiently the problem of crack propagation, the extended finite method(XFEM) was applied to analyse the problem. The extended finite method introduced nodal enrichment functions based on usual nodal shape functions, and traced crack propagation with the level set method. The extended finite method can model arbitrary crack growth without remeshing. This paper simulated the problem of the compact tension specimen with circular hole by extended finite method. The calculation results show that the extended finite method can solve efficiently the problem of crack growth , and the circular hole of compact tension specimen effect the trajectory of mode I crack propagation within certain distance.
