Abstract

The use of shape memory alloy fiber actuators to modify the natural vibration frequencies of a composite beam is investigated. A model system composed of an epoxy matrix with prestrained shape-memory-alloy fibers is used. The natural frequencies of vibration of the beam are measured in a clamped configuration. When electrically heated, the fibers undergo a reverse martensite-to-austenite transformation. Since the geometry of the fibers during the transformation is restrained by the constraints of both the matrix and the clamping device, a recovery force is generated. This force leads to an increase in the natural vibration frequency of the whole composite beam. The transformation behavior of the composite is compared to that of the neat fiber.
