Heuristic gradient extensions of classical damage models are established to overcome their spurious mesh dependency. In contrast, an extension of Gurson's model of ductile damage towards the microdilatational theory is presented through a straight‐forward homogenization. FEM simulations prove the regularization capabilities of the model. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
