How to model the plastic zone of a buckling driven delamination in a sandwich panel?

Hello everybody.. Currently, I am working on Delamination of a sandwich panel. The Delamination is in the interface of the upper Aluminium Face Plate and the Adhesive Layer. When the panel is cyclically loaded under compression, the delamination(crack) grows and the aluminium face plate undergoes local buckling, the crack tip undergoes plastic deformation and a portion of the buckled form stays plastically deformed upon unloading. The software used is ANSYS Mechanical 14.5. 

Would I have to compile a new routine for this or is there an inbuilt one in ANSYS regarding this? I know J-Integral and Kinematic Hardening but have no idea how to connect everything together. 

I have decent experience in ABAQUS compared to ANSYS, so if anyone can point me to a tutorial to model the plastic size at the crack tip as the crack grows in any of these two softwares, I would be extremely grateful.

Can anyone help me in this as to how to start with modelling the plastic zone? Thanks in advance..

The problem description is pretty much similar to this already existing question:
