Hey Max, yes, you would use a plasticity material model. Yes, you only take data from the force-displacement curve up to the maximum value. The stress-plastic strain data table will use the last value for larger values of plastic strain in a simulation where the plastic strain exceeds the last value in the table. In a tensile test specimen, that model is sufficient to see the typical necking behavior which reduces the force output at large displacement. See what happens in your compressive simulation.

I recommend the following two courses:
