In order to predict the damage evolution in finite element simulations, a structural theory combined with viscoplastic constitutive equations acounting for damage is used. However, different structural hypotheses, used in the theoretical model, can lead to variations in the numerical result. Therefore, first‐ and third‐order shear deformations theories are applied in a finite element code. Moreover, local and non‐local damage approaches are used. The aim is to determine the numerical model, which leads to the most accurate results compared to experiments. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim) Access State: Open Access
