Abstract：Based on the nonlinear constitutive relations of the giant magnetostrictive material, the nonlinear magnetoelectric(ME) effect of composite cylinder is considered. The influences of magnetic frequency and the thickness ratio of two materials on ME coefficient under different boundary conditions are discussed. Moreover, the effects of pre-pressure and magnetic field on the ME coefficient are obtained. For Tefernol-D/PZT-5 composite, with the increase of pre-pressure, the maximum value of ME coefficient decreased, but the magnetic field corresponding to the maximum value of ME coefficient increased. The result shows that the thickness ratio of two materials has significant effect on the ME coefficient of the giant magnetostrictive/piezoelectric composite cylinder. In addition, the mult-peak values of ME coefficient appear when the magnetic frequency is large.
