I am newbie to Finite Element Method analysis and CalculiX.
I would like to perform dynamic nonlinear contact analysis including the “unloading” part of foamed resin material (HYPERFOAM) with Mullins Effect. How should I do it with CalculiX?
There is the keyword “* MULLINS EFFECT” in Abaqus, but I can’t find it in CalculiX.
I think the loading and unloading parts need to be in separate steps, but is there any way to do it in one step?
If the steps are separated, is it necessary to separate the material definitions and switch the material definitions?
