How I can use a stress-strain curve in the plastic region with the negative elasticity modulus to material’s modelling

RE: negative elasticity modulus
Further, the use of such a construct (even when allowed by codes) almost guarantees severe convergence problems. It completely freaks out the yield surface when solving Mises plasticity problems.
I would discourage this approach.
