Hi!

Im trying to simulate a Prozess with a hyperelastic material. The seal is the hyperelastic material (Silicone) and the the 2 other parts are rigid bodys. Now i want to add an failure criterion with mullins damage. In the next days i get Test Data for my Material. (silicone). I tried to simulate the Mullins damage with parameters i guessed but now the simulation get aborted.

I have Element deletion on and also in my history output the status variables on... I cant find my failure.. Maybe you can help me how i can fix this problem. I add the element control from my inp data maybe it will help. Oh and im working the first time with abaqus.. so maybe describe the solution easily,)

Thanks !
