Piezoelectric Composites

Abstract

The linear theory of piezoelectric viscoelastic materials in incorporated into a finite element code. The code allows specification of general electrical and mechanical boundary conditions and loadings. Applications of the code to problems involving ferroelectric ceramics, ceramic polymer composites and viscoelastic piezoelectric polymer films illustrate the utility of the method. A parametric design study of a ceramic-polymer transducer reveals a strong dependence sensitivity to polymer Poisson's ratio values. The finite element method provides detailed information that can be used to advantage in component design.
