Vibration suppression of structures using smart materials has received considerable attention by many researchers[1-3].Shape memory alloys, piezo-electric, electro-rheological fluids are commonly used smart materials for sensors and/or actuators, magnetostrictive materials are being considered as promising candidates for their dual applicability as sensors and actuators.Terfenol-D is one of several magnetostrictive materials with the property of converting energy into mechanical motion.and vice versa.
