Abstract

When simulating crack propagation process using the finite element method, we need to create singularity grids at the crack tip. And with the increase in crack length, we need a re-division of grids. This makes the calculation very complicated. The extended finite element method (XFEM) is an effective method for simulating crack extension. And the crack is independent of the grids. Because there is no complicated grid at the crack tip in the XFEM model, the computation efficiency can be increased greatly. This paper investigated the fracture behavior of the propellant material with an initial crack using XFEM. By comparing with existing experimental results, this paper shows that XFEM can be used to simulate fracture characteristic of the propellant material efficiently.
