Theoretical modeling results are presented in this paper for magnetoelectric coupling in layered magnetostrictive-piezoelectric structures taking into account the flexural deformations. An exactly solvable model of magnetoelectric effect in symmetric and asymmetric structures is discussed. Explicit expressions for magnetoelectric coefficients in terms of material parameters of composite components are derived to take into account the flexural deformations of magnetostrictive-piezoelectric bilayers. The magnetostrictive and piezoelectric layer thickness ratio dependence is shown to have two peaks and a minimum at approximately equal thicknesses of layers. The theoretical estimates satisfactorily agree with experimental data for cobalt ferrite- lead zirconate titanate bilayer.
