【 摘 要 】

The influence of the interlayer adhesive bonding is considered in bilayer magnetostrictive-piezoelectric structure. The expression for the frequency dependence of the magnetoelectric voltage coefficient in the electromechanical resonance region is obtained using the simultaneous solution of the motion equations for the magnetostrict- ive, adhesive, piezoelectric phases and material equations. It is shown that in the passage to the limits this expression for the coefficient transforms to the expression for ideal connection between the layers.
