Convergence issue in Non-linear Buckling simulation

      I have been doing a non-linear buckling simulation on sqaure sheet with 0.1mm thickness, while doing so i am encountering convergence issue.
      I have tried various ways to tackle it like increasing the substeps, gradually increasing the loads, refining the mesh , but none of them seems to be working.
      I would be greatful if anyone can help me.

      Hi

      Try to use stabilization which really helps with buckling :
