This paper presents the nonlinear electromagneto-mechanical behavior of magnetostrictive/piezoelectric laminated pieces under magnetic fields both numerically and experimentally. The pieces are fabricated using thin Tb 0.3Dy0.7Fe2 (Terfenol-D) and Pb(Zr,Ti)O 3 (PZT) layers, and the magnetostriction of the pieces is measured. A nonlinear finite element analysis is also employed to evaluate the second-order magnetoelastic constants in Terfenol-D layer bonded to the PZT layer, and the nonlinear displacement, internal stresses and induced voltage for the magnetostrictive/piezoelectric laminated pieces under magnetic fields are discussed.
