Abstract

This work presents the nonlinear bending response of magnetostrictive/piezoelectric laminated actuators under magnetic fields both numerically and experimentally. The actuators are fabricated using thin Terfenol-D and PZT layers, and the magnetostriction of the actuators is measured. A nonlinear finite element analysis is also performed to evaluate the contribution of magnetic domain switching to the second-order magnetoelastic constants in Terfenol-D layer, and the effect of magnetic field on the deflection, internal stresses and induced voltage for the magnetostrictive/piezoelectric laminated actuators are discussed in detail.
