Is there a material model that captures compressive behaviour in ANSYS workbench?

[assafwei]

Hi,

I am using a multilinear isotropic hardening with a stress strain curve to model my material. This model only captures tensile strength (I tried adding compressive yield strength criteria but it had no effect).
I am looking for a model that can also describe "multilinear" compressive behaviour.
I tried the "cast iron" material (I have a tension and compression stress-strain curves) but for some reason it has problems converging in tension scenarios.
Is there a material model available through workbench that can use the compression stress-strain curve data I have to also capture the compressive behavior?

Thanks.
