A new viscoelastic constitutive model for continuous media at finite thermomechanical changes (Q1388557)

This paper is concerned with the continuum formulation of a fully coupled thermo-mechanical constitutive model for highly deformable bodies with viscous dissipation. The three-dimensional material law is applicable to the thermomechanical characterization of elastomeric (high-polymeric) solids in the finite strain domain under varying temperature. The description is based on the concept of internal state variables and rational thermodynamics. The main goal of the presentation is to develop consistent constitutive equations for the stress, entropy and independent internal variables such that the second law of thermodynamics, in the form of the Clausius-Duhem inequality, is satisfied.
