Non-linear mechanical, electrical and thermal phenomena in piezoelectric crystals
Mechanical, electrical and thermal phenomena occurring in piezoelectric crystals were examined by non-linear approximation. For this purpose, use was made of the thermodynamic function of state, which describes an anisotropic body. Considered was the Gibbs function. The calculations included str...

crystals were examined by non-linear approximation. For this purpose,
use was made of the thermodynamic function of state, which describes
an anisotropic body. Considered was the Gibbs function. The calculations
included strain tensor εij = f(σkl
, En, T), induction vector Dm =
f(σkl
, En, T) and entropy S = f(σkl
, En, T) as function of stress σkl
, field
strength En and temperature difference T. The equations obtained apply to
anisotropic piezoelectric bodies provided that the “forces” σkl
, En, T acting
on the crystal are known. |
