In this work we propose a new numerical formulation to compute the de- lamination onset and propagation along weak interfaces under mixed-mode conditions. The interfacial problem is addressed through a cohesive crack model, concentrating all the non-linearities at the interface. The accuracy of the proposed formulation is verified against predictions of a combined contact-delamination algorithm.

Abstract
In this work we propose a new numerical formulation to compute the de- lamination onset and propagation along weak interfaces under mixed-mode conditions. The interfacial problem is addressed through a cohesive crack model, concentrating all the non-linearities at the interface. The accuracy of the proposed formulation is verified against predictions of a combined contact-delamination algorithm.File in questo prodotto:
