A model of polarizable media investigated by Maugin and coworkers is considered as the domain of application of a recent method for the geometrization of the thermo-elasticity of continua with internal variables. The polarization together with its space gradient are assumed as state variables expressed in terms of internal varables evolving according to a relaxation law driven by external and internal electric fields. The entropy production in Clausius-Duhem inequalities are calculated explicitly.

Abstract
A model of polarizable media investigated by Maugin and coworkers is considered as the domain of application of a recent method for the geometrization of the thermo-elasticity of continua with internal variables. The polarization together with its space gradient are assumed as state variables expressed in terms of internal varables evolving according to a relaxation law driven by external and internal electric fields. The entropy production in Clausius-Duhem inequalities are calculated explicitly.File in questo prodotto:
