Abstract

This work deals with the dynamic electromagneto-mechanical behavior of clamped-free giant magnetostrictive/piezoelectric laminates under AC electric fields both numerically and experimentally. The laminate is fabricated using thin magnetostrictive Terfenol-d and piezoelectric PZT layers. The magnetic field-dependent magnetoelastic constant and domain wall motion effect were incorporated to describe the nonlinear behavior of Terfenol-d and PZT layers, respectively, and three-dimensional finite element analysis was employed to calculate the displacement, stress and induced magnetic field. Experiments were also conducted to measure the displacement and induced magnetic field for the magnetostrictive/piezoelectric laminates under AC electric fields. Comparison was then made between simulation and experiment.
