Abstract
Shape memory alloys were used as caps for the 'cymbal' flextensional transducer. The active caps provide a tunable resonance frequency and a damage recovery mechanism associated with the alloy's martensitic phase transformation. These two concepts were investigated and a 25% change in resonance frequency was observed for Ni-Ti alloy caps. It was also demonstrated that complete shape recovery could be achieved after hydrostatic pressures buckled the transducer caps. Cap deformation and recovery were demonstrated with profilometer and dh measurements.
