Defining Plastic Material Model with Different Yield Strength

Question - How to define a plastic material model with different yield strength in tension and compression?

Answer - Sometimes, it may be needed to define a different yield strength in tension and compression for the same material, especially for nonlinear materials. While a sophisticated material model is needed for such a purpose, this may also be defined by using the cast iron material model. This model uses the same elastic modulus in both tension and compression but one may define multilinear isotropic hardening model with different curves in both tension and compression. In the attached example model, we demonstrate how to use the cast iron model in Workbench Mechanical.
