Abstract
In this paper, Onsager’s principle of irreversible thermodynamics is applied to viscoelastic materials subjected to finite deformation. The constitutive equation of Ref. [10] for small dynamic strains superposed on a finite static deformation is used. The state of the resulting deformation can be considered as a small deviation from an equilibrium reference state. The latter is the state of equilibrium of a material subjected to a finite deformation in which the material is maintained for a long time.
