Cohesive elements are useful in modeling adhesives, bonded interfaces, gaskets, and rock fracture. The constitutive response of these elements depends on the specific application and is based on certain assumptions about the deformation and stress states

surface to cohesive elements. When these cohesive elements are modeled the behavior of the model is however completely incorrect. The input (.inp) files for both the cohesive surface and the cohesive element fibre-epoxy interaction can be found here: Cohe

The “trick” is to use cohesive elements or cohesive surface contact. This modeling approach has been around for many years but many people are still struggling to set it up properly. In this article I will try to demonstrate, by example, how this work
