โœฆ Synopsis

In this paper\ three displacement functions are introduced to simplify the basic equations of a radially polarized\ spherically isotropic\ piezoelectric medium[ By expanding the displacement functions as well as the electric potential in terms of spherical harmonics\ the basic equations are converted to an uncoupled Euler type\ second!order ordinary di}erential equation and a coupled system of three such ones[ Based on the well!known solution to the Euler equation\ the general solution for the static problem is obtained[ Some axisymmetric problems are then considered[ It is noted that the present analysis is an extension of that of spherically isotropic pure elasticity "Chen\ 0855#[

In this paper, three displacement functions are introduced to simplify the basic equations of a radially polarized, spherically isotropic, piezoelectric medium with radial inhomogeneity. For the general non-axisymmetric free vibration problem, it is shown that the controlling equations are "nally re

Electroelastic equations are established for the axisymmetric vibrations of radially polarized piezoelectric ceramic long tubes, whose cylindrical surfaces are electroded and subjected to an alternating voltage. Closed-type solutions are obtained for the mechanical radial displacement and electric p
