Due to their high specific strength and stiffness, carbon fibre‐reinforced polymers (CFRP) are widely used in several fields of engineering, e.g. aerospace engineering. A new design scheme aims for the exploitation of material reserves. Since design is always linked to expensive experimental investigations, reliable simulation procedures are required to lower the related costs. In terms of detecting ply failure several criteria have been proposed. In this work those of Hashin [1] and Puck [2] are applied to several numerical models and compared to experimental results [3].
