Hello,


Can you insert a contact tool and check the status to see whats happening? Try to even increase the number of sub-steps so that the loads are applied more gradually and increase the pinball radius.


Also, what contact algorithm are you using?


Based on what you have described I think it would help if you used a nodal contact detection instead of the defaults (gauss integration points).


Checkout this useful article and see if it helps?
