    Indentation with two materials: convergence problems

    I want to model an indentation. The part wich is indented by a punch is made of two materials with different yield stress. I noted that when I use the values 376 and 200 MPa for Yield Stress everything is ok. But if I choose 376 and 110 MPa the job is aborted because of convergence problems. It...

    Strange Meshes in symmetric parts

    I created a model that has symmetric parts. When I decide to run an analysis with half of the model I have good results, but when I try the entire model the solution diverges at the end of the analysis. When I look the results I can see that there is a big difference between the response of the...

    Convergence Problems

    I have started using Abaqus few months ago, so this might be a simple problem but I can't solve it. In my model I must set a displacement of one rigid part that becomes in contact with a deformable part. But it only works when the displacement is small. When I use a large displacement the job is...
