Approaches for numerically-analytical solution of boundary-value problems of the linear theory of electroelasticity and hydroelectroelasticity are developed. Solutions of new problems about non-axisymmetric vibrations of infinitelly long circular cylindrical shells made of polarized in thickness piezoceramics with mixed system of electrical boundary conditions are obtained and analyzed. Control of radial vibrations of a hollow piezoceramic cylinder submerged in boundless acoustic environment by electric signal is investigated. Using Laplace integral transform initial problems is reduced to the Volterra integral equations 1st kind or to their systems, the solutions of which is implemented numerically using modern calculating algorithms. Investigation of piezotransducers deformations is made on model based on the Kirchhoff-Love hypotheses generalized to the case of electro-mechanical systems. The evaluation of results reliability and adequacy of used hypotheses is presented.
