DETERMINING THE VISCOPLASTIC PARAMETERS OF RUBBER-TOUGHENED PLASTICS

Abstract

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

Keywords:
