Electromagnetomechanical media including irreversible processes and interfacial properties

A nonlinear theory of deformable piezoelectric and ferroelectric media including thermal and electronic dissipative phenomena, as well as thermomechanical and electromagnetic interfacial properties, is presented. The latter is formulated through a gauge and rotationally invariant, thermodynamically admissible energy approach. The attention is focused on electromagnetomechanical couplings and on the interfacial properties that cannot be approached safely through conventional methods.
