An efficient low order virtual element method (VEM) the phase field modeling of ductile fracture is outlined in this lecture. The recently developed VEM is a competitive discretization scheme for meshes with highly irregular shaped elements. Also the phase-field approach is a powerful technique to simulate complex crack phenomena in multi-physical environments. The formulation in this contribution is based on a minimization of a pseudo-potential density functional for the coupled problem undergoing large strains. A main aspect of this formulation is the extension towards VEM due to its flexibility in dealing with complex shapes and arbitrary number of nodes.
