Abstract

Modelling of thin joining zones is one application of Cohesive Zone Elements (CZE). It is shown that Traction Separation Laws (TSLs) used as constitutive models in most CZEs that can be found in literature cannot fully capture all damage causing deformation modes induced by forming of hybrid components. In this contribution we present an approach to overcome this deficiency by using bulk material models within a Cohesive Zone Element. Numerical examples demonstrate the excellent properties of the method by comparing the new formulation with volumetric modelling of a joining zone.
