Adhesive is PMMA cement modeled as solid elements. And adherends are Cobalt chrome alloy and a bone replica (Saw Bones Foam). I modified the surface contacts to include a weld failure model parameter for the maximum shear stress when damage initiates.

Sorry, I forgot to include my question. Would anybody know any techniques to model a bond delamination failure to predict failure loads?

Hello, I am trying to model an adhesive failure with an instantaneous failure, and the adhesive gets completely delaminated from both surfaces at the same moment. It seems not to fit into the cohesive zone model as there is no failure within the adhesive itself. There is a weld failure model...
