A mathematical formulation of the boundary problems of mathematical physics is made, sequential solution which allows describing the stress-strain state and the transfer characteristics of the piezoelectric elements with surfaces partial covering by electrodes. The set of formulated boundary problems makes mathematical content of energy-power method of analysis of the physical condition of the piezoelectric elements in the regime of forced oscillations under the influence of an external source of electrical energy. The proposed sequence of computational procedures can be used in the study of forced oscillations of microelectromechanical structures.
