Applied theory of flexural vibrations of a piezoactive bimorph in the framework of an uncoupled boundary-value problem of thermoelectroelasticity

In this paper, we consider transverse steady oscillations of a piezoactive bimorph in the formulation plane deformation. The problem is solved within framework linear thermoelectroelasticity, while temperature separately and distribution taken into account constitutive relations electroelasticity. On basis Kirchhoff-Love type hypothesis for mechanical quantities symmetric quadratic electric potential, an approximate theory calculating vibrations constructed. Numerical experiments have been carried out various cases pinning excitation vibrations. results these were compared with calculations made using finite element method COMSOL package showed adequacy constructed low-frequency region.
