The Gurson-type model considered here deals with a nonlocal stress state which implies nonlocal equilibrium conditions as well as nonlocal constitutive equations. However, it is assumed that the kinematic equations of the theory of simple materials are still valid. The nonlocal Gurson-type model has been implemented into the finite element program Abaqus using its user material facility. The regularization behaviour of the model is discussed by means of typical two dimensional localization problems.
