Hi Andreas,Â
Thank you very much for the response. I have learnt a lot from your advice.
The material erosion criteria I have been using is by UMAT. But it starts to give negative volume error, after adding CONTACT_EROSION_SURFACE_TO_SURFACE for all contact surface and taking high principle stress values in MAT_EROSION the entire plate gets deleted. What is the contact which I need to use to solve the problem.Â
The following image is of the elements gets deleted.
Thanking you
