Vibrations of a hollow circular cylinder of piezoelectric ceramics

The wave propagation in a piezoelectric hollow cylinder of class (6-mm) crystals or ceramics (m) with traction-free surfaces is studied. The frequency equations are obtained subject to various types of electrical boundary conditions and are examined numerically for the piezoceramic material PZT-4; the results are presented graphically as well as in tables. © 1987, Acoustical Society of America.
