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
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.
