Paper Abstract

Focus is here made on the approximate modal coupling evaluation and response analysis of the piezoceramic materials d15 shear-mode response. Hence, different evaluation techniques of the effective modal coupling are assessed and twodimensional (2D) plane strain and plane stress free-vibration problems, under short-circuit and approximate, without equipotential (EP) constraints, and accurate, with EP, open-circuit electric conditions, are investigated with ANSYSr 2D and three-dimensional finite elements for a literature shear-mode piezoceramic sandwich beam benchmark with different filling foams. It is shown that the EP physical constraints reduce dramatically the effective coupling, and the plane stress and strain results depend strongly on the filling foam stiffness.
