A phase field model for ductile fracture with linear isotropic hardening is proposed. The chosen coupling between the fracture field and the elastic‐plastic material law is chosen such that a monolithic iteration scheme to solve the discretized partial differential equations for the evolution of the fracture field and for the mechanical field is feasible. 3D examples of ductile fracture are considered.
