In this work we consider some expressions for the free energy, already proposed and studied for viscoelastic solids, in order to adapt them to incompressible viscoelastic fluids. The internal dissipation, corresponding to each of these various forms of the free energy, is also evaluated. In particular, the form of the minimum free energy for the discrete spectrum model is also considered in order to show its equivalence with some classical free energies.

Abstract
In this work we consider some expressions for the free energy, already proposed and studied for viscoelastic solids, in order to adapt them to incompressible viscoelastic fluids. The internal dissipation, corresponding to each of these various forms of the free energy, is also evaluated. In particular, the form of the minimum free energy for the discrete spectrum model is also considered in order to show its equivalence with some classical free energies.File in questo prodotto:
