摘要

Transient stresses developed in a cylindrical shell of non-homogeneous dielectric material (piezo- ceramic) due to applied voltage have been determined. The solution of the electromechanical problem involving electrostatic equation, equation of elasticity and the constitutive equations of piezoceramic materials is presented in terms of the confluent hypergeometric function and a particular integral of a new type, the D-function. The variation of stress components with radial distance is presented graphi- cally. This study helps to choose the composition of the material for construction of the shell.
