dc.description.abstractThis paper addresses the free vibration, dynamic response, and theactive control of composite rotating pretwisted blades modeled asnonuniform thin-walled beams, fixed at the hub at a settingangle, and incorporating piezoelectrically induced dampingcapabilities. In this sense, a distributed piezoelectric actuatorsystem activated through the application of an out-of-phaseelectrical current is used to suppress the dynamic response of therotating beam subjected to a Heaviside pulse. The blade modelincorporates nonclassical effects such as transverse shear,secondary warping, and rotary inertias, and includes thecentrifugal and Coriolis force fields. A velocity feedback controllaw relating the piezoelectrically induced bending moment at thebeam tip with appropriately selected kinematical responsequantities is used, and the beneficial effects of itsimplementation upon the closed loop eigenvibration and dynamiccharacteristics of the blade are highlighted.en
