This paper describes the material parameter determination procedure for the elasto-viscoplastic Bodner-Partom model. A set of viscoplastic parameters is determined for rubber-toughened propylene-ethylene copolymer, and is used to numerical simulations of the material behavior under different strain rate deformations. The evaluation of material parameters for Bodner-Partom constitutive equations is carried out using tensile tests.
