摘要：
The propagation of shear horizontal waves in laminated piezomagnetic/piezoelectric plates was investigated using the ordinary differential equation and stiffness matrix methods. Commonly used materials, namely barium titanate as piezoelectric ‘B’ and cobalt ferrite as piezomagnetic ‘F’, were retained for illustration. The dispersion curves of the first five modes were shown for different sequences F/F, B/B, and F/B. The effects of thickness ratio on phase and group velocities as well as the influence on the magneto-electromechanical coupling factor of the first mode were investigated. Large magneto-electromechanical coupling factors could be achieved by an appropriate adjustment of the thickness ratio. The present investigation is of practical interest for developing new layered composites made of smart piezoelectric and piezomagnetic devices for engineering applications.
