Hi Douk,

If you have your stress-strain curve available, I would suggest you to employ the Multilinear Isotropic Hardening model available in Engineering Data (picture below) and then proceed to more complex models if necessary. Once you select this model, you can input your stress-strain data in the form of tabular data.
Note that this plasticity model uses the *MAT_PIECEWISE_LINEAR_PLASTICITY model of LS-DYNA that is based on isotropic von Mises plasticity and isotropic hardening, and you can refer to the help documentation for the available options and more details about this model.
