Abaqus: Composite delamination with cohesive elements



I have to do a FEA regarding impact damage and delamination propagation in a CFRP specimen.

I have to do this using cohesive element in order to see the propagation of the delamination front in the material.

My problem is that I don't know how to do this in Abaqus.

I'll better explain: I can use this software but is the first time approching composite behavior and I really don't know how to model that.

I've done many attemps (using cohesive element and tie constrains or cohesive interaction as well) but I've always faced problems about the implementation.

Can you tell me what is the right way to do this? Or if someone has already solved this issue, where can I found the solution?

Thanks for every help you could provide me,

Maria Pia
