Abstract: Three-dimensional solutions for free vibration of the magneto-electric-elastic multilayered rectangular plates were investigated. Based on the three-dimension elastic theory and piezoelectric-piezomagnetic theory, the dynamics equation of the laminate with magnetoelectric effect was deduced. The solution for simply-supported panel was obtained by employing the power series method. The effect of the plate as a sensor and as an actuator on the vibration frequency was analysed. The calculating result for the piezoelectric mono-player is compatible with that in the previous paper. The influence of the thickness and the sequence of layers on the vibration frequency was discussed. When the volume fraction of the middle layer increases from 25% to 75%, the frequency varies gently.
