Abstract
In this paper, based on the constitutive equations of piezoelectric effect and piezomagnetic effect, a 1-3 model of laminate magnetoelectricity composite materials is established. By combining material mechanical kinematic equations and circuit state equations, magnetical-mechanical-electrical equivalent circuit of laminate magnetoelectric composite materials is raised and magneto-electricity switch effect is analyzed. Upon these, a new kind of laminate magnetoelectricity composite material, Terfenol-D/PMNT/Terfenol-D, is put forward. Taking 1-3 model as an example, with the help of MATLAB, we simulate and calculate the magnetoelectric response of this new material. Through calculation, a conclusion is drawn that this new materials magnetoelectricity switch coefficient is higher than that of Terfenol-D/PZT/Terfenol-D. This theoretical basis will put this new material in a good position in magnetoelectric materials preparation.
