Hi all
I want to simulate the deep rolling process(as seen as in attachment)
in this model I defined 2 steps,at first, the rigid ball create a pressure to cylinder to create residual stress and at the second step the ball begins displacement with
a low speed in direction of cylinder longitude to create surface overlap, while the cylinder is rotating in both steps.
in this model I have used the explicit solver but it takes too much time and elements convergence cannot be accomplished.
how can i reduce the time of my solution?
