Nonsteady hydroelasticity of a system of coaxial piezoceramic cylindrical shells during electrical excitation

3D free vibration analysis of a functionally graded piezoelectric hollow cylinder filled with compressible fluid

“…Chen and Ding (1999) employed a displacement separation formula to simplify the basic equations of a transversely isotropic medium and considered the vibration of a fluid-filled transversely isotropic cylindrical shell. The coupled analysis of piezoelectric cylindrical shells has also attracted particular interests, since it is essential for their frequent encounters in some engineering applications (Babaev and Savin, 1988;Babaev et al, 1990;Shulga and Melnik, 1996;Ding et al, 1997a). The 3D coupled free vibration of a fluid-filled piezoelectric hollow sphere was considered by employing the Frobenius power series method.…”

Electric to acoustic conversion by a spherical piezoceramic shell with shields

“…Applied hydroacoustics is currently interested in the use of electric pulses with a complex law of voltage variation for the nonstationary excitation of piezoelectric transducers. The overwhelming majority of the available publications on the nonstationary hydroelectroelasticity of thin-walled piezoceramic shells studies the nonstationary behavior of cylindrical shells [1][2][3][4][5]. Those few publications that address transient modes in spherical piezoceramic shells [11], spherical piezoceramic shells with inside impedance shield [12], and two concentric spherical piezoceramic shells [1, 6] do not provide methods and a theory for the development of modern sonar systems.…”
