As a first step, you could evaluate the risk of delamination using a failure criteria such as Puck 3D. See the ACP documentation for more informaiton:
If you want to explicitly model the delamination and have ply separation, you could do this using interface layers in ACP:
Here is more information from the ACP doc:
If you have access to the Ansys Learning Hub (ALH), you will find a workshop on delamination in the following training course:
Let me know how it goes.
