THE OPEN-CIRCUIT SENSITIVITY OF RADIALLY POLARIZED FERROELECTRIC CERAMIC CYLINDERS
Abstract
The open-circuit sensitivity of radially polarized ferroelectric ceramic cylinders is derived by treating the ceramic as an anisotropic material. The analysis demonstrates that if the anisotropic properties of the materials employed in the design of cylindrical hydrophone elements are considered, the resulting sensitivities are not significantly different from those derived by Langevin, who considered only stress distributions that obey isotropic criteria. Graphs of the open-circuit sensitivity versus the ratio of wall thickness to outside diameter are presented for the two dissimilar approaches that define the regions over which the differences may be neglected.
