Summary

Polymers and biological materials are often considered hyperelastic isochoric materials with a relevant viscous behavior. The behavior of these materials is often anisotropic due to reinforcing components laid up during manufacturing or by nature. In this paper we present and compare two different formulations developed for anisotropic materials which sustain large strains and contain a viscous dissipative behavior. We use a phenomenological, continuum-based approach. These formulations are valid for large deviations from thermodynamic equilibrium and can be coupled with any available anisotropic large-strain stored energy. Even though one formulation is based on the Sidoroff multiplicative decomposition and the other on a reversed decomposition, a parallelism between both formulations is apparent. Furthermore, for the case of moderate large strains, anisotropic hyperelasticity and isotropic viscosity, we show that we obtain similar predictions in the given examples.
