Abstract
We study the theory of the basic vibration characteristics of a circular cylindrical shell piezoelectric transducer. The linear theory of piezoelectricity is used. Both the free-vibration solution for resonant frequencies and modes as well as the electrically forced-vibration solution for admittance are obtained. Numerical results are presented.
