This work deals with the detection and response characteristics of clamped-free giant magne-tostrictive/piezoelectric laminates under concentrated loading both numerically and experimentally. The laminate is fabricated using thin magnetostrictive Terfenol-D and piezoelectric PZT layers. Three dimensional finite element analysis was carried out, and the electromagneto-mechanical fields in the two and three layered magnetostrictive/piezoelectric laminates were predicted by introducing a second-order magnetoelastic constant of Terfenol-D. The tip deflection, induced voltage and induced magnetic field were also measured, and comparison was made between simulation and experiment to verify the model.
