Abstract
The aim of this paper is to develop a micromechanical method based on a proper representative volume element to investigate the effective coefficients and fully coupled electromagnetoelastic responses for three-dimensional smart composites. Relations between the particulate volume fraction, effective moduli, piezoelectric coefficients, and dielectric coefficients are investigated for the composites. Their effective responses, with account of electric, magnetic, and displacement fields, are analyzed. The numerical results obtained indicate that the overall strains of piezoelectric-piezomagnetic composites strongly depend on variations of the electric and magnetic fields.
