Abstract

Flow-induced resonance can damage structures ranging from skyscrapers to aircraft. Shape Memory Alloys (SMAs) offer a way to control the natural frequency of structures and avoid resonance without adding significant weight. In this project, the resonance velocity of a 0.06- inch diameter Nickel Titanium SMA wire in a subsonic wind tunnel was controlled using resistive heating. It was found that the velocity at which the wire resonated varied with the square of the power applied to it.
