Properties of cohesive surface on cohesive elements

Hello everyone,

I have a simple ABAQUS model with cohesive surface and I want to create a comparable model with cohesive elements instead of the surface. Applying the same properties onto the cohesive elements does not give me the desired results. Then I read somewhere that the properties cannot be applied on the elements directly the same way.

So how do I apply my interface properties onto the material of the cohesive elements? I thought that I should consider the thickness of the elements, but still until now I have not succeeded yet...

Thank you in advance.
