dc.description.abstractA number of issues related with the vibrational behavior of rotating blades modeled as pretwisted thin-walled anisotropic beams, incorporating adaptive capabilities are addressed. The adaptive capabilities are provided by a system of piezoactuators bonded or embedded into the structure. Based on the converse piezoelectric effect and on the out-of-phase activation, boundary control moments are piezoelectrically induced at the beam tip. A feedback control law relating the induced bending moments with the kinematical response quantities appropriately selected is used, and its beneficial effects, considered in conjunction with that of the beam anisotropy and structural pretwist upon the closed/open loop eigenvibration characteristics are highlighted.en
