Abstract

A dual reciprocity based boundary element approach for the analysis of magneto-electric laminates free vibration behavior is presented. The problem is formulated employing generalized displacements, that is displacements and electric and magnetic scalar potentials, and the corresponding generalized tractions. The generalized boundary integral representation is deduced by extending the reciprocity theorem to magneto-electro-elasticity problem and the multidomain boundary element technique is used to model multilayer structures. The magneto-electro-elastic static fundamental solutions are used jointly with the dual reciprocity method to transform the inertia domain integral into a boundary integral. Numerical results are presented focusing on the effects of the electro-magnetic poling directions.
