Iv. Vovk et Vn. Oleinik, SOUND EMISSION FROM A WATER-FILLED PIEZOCERAMIC SHELL WITH AN UNSYMMETRICAL INSERT, Acoustical physics, 40(2), 1994, pp. 196-200
The problem of the emission of sound by an infinitely thin cylindrical
piezoceramic shell connected to an unsymmetrical insert through a lay
er of water is solved by the partial regions method. Spectral and dire
ctivity characteristics are evaluated for some insert geometries.
