## Abstract A methodology for the simulation of quasiβstatic cohesive crack propagation in quasiβbrittle materials is presented. In the framework of the recently proposed extended finite element method, the partition of unity property of nodal shape functions has been exploited to introduce a highe

The bi-parametric criterion applied to mixed mode brittle and quasi-brittle fracture is based on the principle that the initiation of crack growth instability occurs when the maximum value of strain energy density, evaluated along the initial elasticcplastic boundary around the crack tip, is equal t
A new approach of dealing with mesh dependence in finite element modelling of fracture processes is introduced. In particular, in brittle fracture modelling, the stress concentration is mesh dependent as the results do not stabilise when refining the mesh. This paper presents an approach based on th
