Viscous and elastic-plastic material model in the ABAQUS

Abstract

The implementation of constitutive equations into a structural analysis computer program is investigated. The material model under consideration describes pure linear elastic, elastic-plastic and viscous deformation mechanisms. The elastic-plastic material model assumes isotropic hardening and the uniaxial stress-strain curve is bilinear. The von Mises yield condition is applied. Viscous deformation is described by the equation proposed by Le Gac and Duval. This model is coded into the ABAQUS finite element method program. The time integration is carried out by the Euler forward method. The computed examples show that the implementation is carried out successfully.
