It is now possible to add Viscoelasticity to a Hyperelastic Material to simulate large strain viscoelastic applications.The set of isotropic hardening models in plasticity has been extended with four new built-in models: Ludwik, Swift, Voce, and Hockett-Sherby.The kinematic hardening in plasticity has been extended with the Armstrong-Frederick and Chaboche models.Time derivatives of the components of plastic strain are now available, so it is possible to use expressions like d(solid.epe,TIME) to create strain-rate-dependent plasticity models.New variables have been added for incompressible hyperelastic material models: the volumetric and isochoric strain energy densities. The volumetric strain energy density is usually defined as <solid>.Wsvol, where <solid> is the tag of the Solid Mechanics interface where the Hyperelastic material node is defined. The isochoric strain energy density is defined as <solid>.Wsiso.When using the Nearly incompressible formulation, the new variable <solid>.Uvol is defined as Wsvol was defined in previous versions. The variable Wsiso is now defined in terms of the auxiliary pressure <solid>.pw.
