Abstract: Perzyna model in viscoplasticity has. been studied by the parametric variational principle, which could be transformed into solving the parametric quadratic programming problem. The FEM form of this problem and its implementation have also been discussed in the paper.

Key words: viscoplasticity, parametric quadratic programming, FEM
