Abstract

This work presents the nonlinear bending response of magnetostrictive/ piezoelectric laminated devices under electromagnetic fields both numerically and experimentally. The devices are fabricated using thin Terfenol-D and PZT layers. The magnetostriction of the Terfenol-D layer bonded to the PZT layer is measured, and a nonlinear finite element analysis is performed to evaluate the second-order magnetoelastic constants in Terfenol-D layer using measured data. The deflection, internal stresses and induced voltage/magnetic field for the laminated devices under magnetic/electric fields are then discussed in detail.
