Relaxation Functions in Thermo-electro-viscoelasticity

In paper [2] the theory [1] for a thermo-electro-mechanical simple body with fading memory is used to set up a thermo-electro viscoelastic theory, which is obtained by a linearization procedure and the Riesz representation theorem. This is done within the Green-Naghdi scheme of thermodynamics. Hence several restrictions on the various relaxation functions are found that extend the ones in [3] for finitely thermoviscoelastic materials. The restrictions are obtained from an internal dissipation inequality that is a consequence of a dissipation inequality.
