Abstract: An unsteady problem of electroelasticity for a long radially polarized anisotropic piezoceramic cylinder with normal stresses that are arbitrary functions of time applied to the radial surfaces is considered. A closed solution is constructed by the method of expansion with respect to eigen vector-functions. This solution allows determining the frequencies of natural oscillations, the stress-strain state of the element, and the potential and intensity of the induced electric field.

Keywords: coupled problem of direct piezoeffect, long cylinder, axisymmetric dynamic load.
