Problems with convergence in deep drawing processes with different friction coefficient

I have encountered a situation in a simulation of a deep drawing process of a metal sheet. When I decrease the friction coefficient from 0.57 (steel-steel) to 0.4 or 0.2, the model doesn´t convergence, whereas with the first value, it reaches out a solution. Does anybody have a hint to solve it?
