Abstract:

The open-circuit sensitivities of radially polarized ferroelectric ceramic spheres are derived from the viewpoint of treating the ceramic as an anisotropic material. The results are in good agreement with similar sensitivities predicted on the basis of isotropic stress distributions. Graphs of the open-circuit sensitivity versus the ratio of wall thickness to outside diameter for several different ceramic materials indicate the region over which the spherical elements may be considered to be thin-walled spheres. Included for comparison are the sensitivities of similar ceramic spheres that are not pressure-released on the inside surface but are in immediate contact with a solid sphere. Also included are graphs of the magnitude of the stresses induced in the spheres by the ambient hydrostatic pressures.
