Abstract

The extended finite element method (XFEM) is a new numerical method for modelling discontinuity. The application of XFEM in simulating crack propagation in rock masses is investigated. This method greatly eases the modelling of crack propagation as no remeshing is required. The application of XFEM to rock mechanics is presented. A two‐dimensional and a three‐dimensional numerical examples are compared with the experimental results from the literature and good agreements are reached. The XFEM proves to be a promising powerful tool in modelling discontinuities in rock masses.
