Problem description

The verification tests in this section consist of one-element models that are subjected to uniaxial loads in a sequential import analysis. The material model is defined using the parallel rheological framework and consists of an elastic-plastic equilibrium network with Mullins effect and three nonlinear viscoelastic networks. The viscous response in the viscoelastic networks is modeled using the power law, strain hardening, and hyperbolic-sine creep models. Three different strain energy potentials, neo-Hookean, Ogden, and Arruda-Boyce, are considered. The results are transferred from the middle of the analysis and are allowed to continue in the import analysis.

Results and discussion

The results demonstrate that the material models defined using the parallel rheological framework transferred successfully between Abaqus analyses.
