I am trying to simulate "Forming to Welding" and "Welding to Forming". I heard that we have to do Additive Plasticity Solution for "Forming to Welding" and Multiplicative Plasticity Solution for "Welding to Forming". My questions are:
(1) What do these (Additive and Multiplicative Plasticity Solution) mean actually? Do we need to use this?
(2) How to do that in MSC Marc?
Thank you.
