Grid approximations for different types of piezoelectric polarization of spherical and cylindrical bodies were constructed , and appropriate algorithms for solving two-dimensional problems were developed. The results of numerical study of unsteady axisymmetric electroelastic vibrations and stress-strain state under various boundary conditions in the case of radial polarization of rotation bodies were presented. A numerical method for finding EMF during the non-stationary mechanical loads for circular and annular piezoceramic plates with different grip conditions was proposed.
