Abstract

The modelling of a crack propagation through a finite element mesh is of prime importance in fracture mechanics. We propose here a solution based on an advanced remeshing technique. A fully automatic remesher enables us to deal with multiple boundaries and multiple materials. The propagation of the crack is achieved with both remeshing and nodal relaxation. We propose here three different crack growth criteria and compare their respective accuracy. Several examples are shown to demonstrate the robustness of our technique, and to study specific features of each criterion.
