Parallel rheological framework

The parallel rheological framework:

  • is intended for modeling polymers and elastomeric materials that exhibit permanent set and nonlinear viscous behavior and undergo large deformations;

  • consists of multiple viscoelastic networks and, optionally, an elastoplastic network in parallel;

  • uses a hyperelastic material model to specify the elastic response;

  • can be combined with Mullins effect;

  • bases the elastoplastic response on multiplicative split of the deformation gradient and the theory of incompressible isotropic hardening plasticity;

  • can include nonlinear kinematic hardening with multiple backstresses in the elastoplastic response in Abaqus/Standard; and

  • uses multiplicative split of the deformation gradient and a flow rule derived from a creep potential to specify the viscous behavior.
