Cyclic elastic-plastic simulation
I'd like to simulate the total displacement and total plastic strain of a part which suffers cyclic plastic strain. The force is alternating between 0 and a constant maximum force and it is applied slowly. So in every cycle the cross section of the part should be decreasing, the stress should be increasing and the plastic strain should be increasing.
My first idea was to simulate this as a static structural simulation using isotropic hardening. The problem is that the total displacement and plastic strain is not increasing due to the cyclic loading. When using a transient structural simulation the total displacement and plastic strain is increasing a little bit in every cycle. What is the difference? Is the decreasing of the cross section considered by the static and transient analysis? The part is quite complicated, so I prefer the static structural analysis. What is the best way to do this?
I use Workbench 19.
Thanks for your help
