I am attempting to model the compression of a simple cube made of ABS material and obtain the stress strain curve and compare the simulation with the experimental data.

I have made compression samples and obtained the true stress and strain and used an isotropic multilinear hardening model for plasticity.

should I use static, quasistatic, explicit to simulate this. I tried static and in the results couldnt see the elastic region of all curves.

Here also is the material model

Here also is the experimental data ( look at columns D and E )

what is your compression rate say 0.001/s or 1/s. this rate will describe what simulation conditions to used,Most of the compression test are qusic static.
cheers, Ram
