THERMODYNAMICS OF PIEZOELECTRIC MEDIA WITH DISLOCATIONS

In this paper we apply a geometrical theory of thermodynamics with vectorial and tensorial internal variables to a non-conventional model of piezoelectric crystals with dislocations, where a dislocation core tenser a la Maruszewski, its gradient and its flux describe the internal structure of these media. Using the concepts of process and transformation we derive the relevant structure of the entropy 1-form with the explicit existence condition, of the entropy function.
