The magnetoelectric response of magnetostrictivepiezoelectric laminate composites has been investigated. Based on the piezoelectric and piezomagnetic constitutive equations, and motion equation for the composite plate, the magnetoelectric equivalent circuit has been derived, and the magnetoelectric coefficients predicted. Prototype devices of, as an application example, Terfenol-DPZT composite plates were fabricated, and experimental values for the magnetoelectric voltage coefficient coincided with the predicted ones.
