Hi
For " The strain increment has exceeded fifty times ... " problem:
1-Decrease the size of the loading.
2-Reduce the size of the initial time.
3-Reduce the size of the mesh.
4-Use " Specify dissipated energy fraction" in automatic stabilization at the step module.
For " Displacement increment for contact is too big. " problem:
1-Check BCs
2- use unsymmetric matrix storage (Step module>>Other>> Equation solver)
3-Check contact normals or using automatic tolerance in contact control.

Everything is working well. But unsymmetric matrix storage increase the calculation time.
Yes, it works, and your warnings solved, nevertheless this option increases the calculation time.
Be aware that the automatic stabilization may change results if your stabilization is too large.
Good point. I will follow your advice.
Now, Automatic stabilization is= 0.005
I have followed the instruction of Meysam Ghorbanpoor and my model runs perfectly without showing these warnings.
