This paper examines a new concept of adaptive tuned dynamic vibration absorbers (ATDVAs) using shape memory alloy (SMA) elements instead of spring elements. Shape memory is a class of alloys that shows a reversible change in crystalline structure. In the martensite phase, the material exhibits a low elastic modulus and yield strength. Subsequent heating of the material induces the change to austenite, with a corresponding higher elastic modulus and yield strength. The result of the phase transformation is a sizable change in the geometry, in the internal tension, a considerable deformation, and a concomitant frequency shift, as in the case where the SMA is used as the stiffness component of a tuned dynamic absorber. In this research, experimental investigations have been focused to verify the capability of an ATDVA to control vibration on a free-free aluminum panel.
