The mesh approximation for different polarization of piezoceramic cylindrical bodies is built and an algorithms solving two-dimensional problems are developed. The results of numerical studies of the axisymmetric harmonic electroelastic vibrations and stress-strain state under various boundary conditions in the case of cylindrical bodies with radial polarization are presented.
