Fale sprężone mechano-termo-elektryczne w stałym ośrodku piezoelektrycznym

We present the problem of coupled mechanical elastic, thermal and electromagnetic fields (the latter most of the cases reduces to the electric field) in a piezoelectric medium in the case of the harmonic plane waves. The considerations are conducted on the basis of the following linear theories: the classical W. Voight theory of piezoelectricity, the more general theory of piezoelectricity based on the coupling of the electromagnetic field with the mechanical field, the quasi-electric theory of thermo-piezoelectricity, R. D. Mindlin's theory of elastic dielectrics with a polarization gradient, the theory formulating both the electromechanical interaction in materials with centrosymmetry and the surface effects pertaining to deformation as well as polarization.
