Progressive Failure Analysis Pin Loaded Composite

Progressive Failure Analysis Pin Loaded Composite

Progressive Failure Analysis Pin Loaded Composite

Hello, I have a problem with Progressive Failure Analysis (PFA) on pin-loaded specimen. So I have 2 plates connected with bolt (I'm using bush on patran). The first plate (upper) is pulled out on the right side with a displacement constraint (displ. constraint define with a node from MPC force). The 2nd plate (bottom) is fixed on the left side. I'm using Puck failure criteria. And for the solution I'm using Implicit Nonlinear (SOL 400/600) with adaptive parameter in the subcases. I set up the maximum step to 0.1, and the minimum step 1e-5.

The problem is, when I set the displacement constraint to 120 mm or higher, the result on .sts file showing an error (job ends with exit number 1, which is an abnormal exit). I've been trying to increase the maximum step to 0.15, but there were no significant results. I'm stuck at the moment. So, please, anyone help me. This is actually my thesis and I don't really have much time. I've attached the Patran file so you could check it and give some solutions. I'd really appreciate your help.

Thank you everyone!

What is the error mentioned in the f06 file?
Could you post this portion such that I could understand the origin of the error.
