The continuum damage mechanics (CDM) model is added to the extended finite element method (XFEM) to provide a model of ductile crack growth. In this model, the criterion for crack growth in the evaluation of ductile materials is the critical damage parameter obtained from continuum damage mechanics. Numerical implementation of the CDM-XFEM model was used to simulate crack growth modeling in comparison with experimental results, and the results are presented in this paper. The CDM-XFEM model
