Abstract
A theory of thermopiezoelectricity for nonsimple materials is developed by incorporating heat flux as an independent constitutive variable. The linearized version of this theory reveals the presence of second-sound effects. A reciprocity relation which involves two processes at different times and a theorem on the uniqueness of solutions are deduced for anisotropic materials. Finally, a variational principle is established.File in questo prodotto:
