Determination of the electromechanical coupling coefficients of porous piezoceramics

Constitutive equations, wave equations and boundary conditions of piezoelectric porous ceramics are analysed theoretically in order to obtain new definitions of the electromechanical coupling coefficients. Expressions for the k/sub 31/, k/sub 33/ and k/sub 1/ are obtained using different methods.
