Title :
Poisson´s ratio for piezoceramics
Author_Institution :

Abstract :
Poisson´s ratios, with respect to rotated coordinate axes, for hexagonal materials, and particularly, poled ferroelectric ceramics, have been obtained. Formulae are given for ceramics of arbitrary orientation and electrical immittance boundary conditions. A number of simple cases are obtained for open-circuit boundary conditions
