Abstract
"Metallic sheathed magnetostrictive wires (MSMW) will be developed for use in fiber reinforced composite structures. These magnetostrictive wires will be based on rare earth intermetallics such as the "giant" magnetostrictive material TERFENOL-D. Thesmart material characteristics of the magnetostrictive wires can be exploited for sensing, actuation, and, in the simplest case, enhanced passive vibration damping. The wire configuration lends itself well to incorporating into fiber reinforced compositestructures. Techniques for fabricating the MSMW materials will be developed and refined to achieve the highest performance. The MSMW material will be characterized in order to assess the quality of the magnetostrictive wires and compare its performanceto traditional magnetostrictive materials. In order to enable dynamic testing, the MSMW will be incorporated into a simple resin-matrix system. Dynamic characterization of the material will demonstrate its capabilities for vibration applicationsincluding damping, sensing, and actuation. Simple models of the material will be developed to improve future development of the technology. Metallic sheathed magnetostrictive wires (MSMW) could be utilized in a wide variety of applications, both militaryand commercial. Because of their configuration and durability, these wires could easily be incorporated into structures made of resin matrix fiber composites. Once implemented into composite st
