The three-dimensional state equation was derived for a
cylindrically orthotropic piezoelectric body with radial polarization.
The layerwise method was employed to transform the state equation with
variable coefficients to that with constant coefficients and the
state variable solution was obtained. The free vibration problem of a
fluid-filled multi-layered piezoelectric cylindrical shell was then
analyzed. Exact form of frequency equation was presented and numerical
results were obtained.
