This work deals with the formulation of a thermodynamically consistent, isotropic damage cohesive model for mixed-mode delamination under variable mode ratio. The proposed model is based on the introduction of an internal friction angle in the tensile case, that allows for an accurate modelling of the interaction between normal and shear openings.

Abstract

This work deals with the formulation of a thermodynamically consistent, isotropic damage cohesive model for mixed-mode delamination under variable mode ratio. The proposed model is based on the introduction of an internal friction angle in the tensile case, that allows for an accurate modelling of the interaction between normal and shear openings.
