Résumé

In a previous paper, in a geometrized framework for the description of simple ma- terials with internal variables, the specific example of defective semiconductor crystals defective by dislocations was considered and a dislocation core tensor `a la Maruszewski and its flux were introduced as internal variables in the state space. Moreover, the entropy function and the entropy 1-form, starting point to introduce a thermodynamical phase space, were derived. In this contribution Clausius-Duhem inequality for these media is exploited, and, using a Maugin technique, the laws of state, the extra entropy flux and the residual dissipation inequality are worked out. Also, following Maugin, the heat equation in a first and a second form is derived. [DOI: 10.1685/CSC09308] About DOI
