Abstract
This paper deals with the control of the dynamic response of cantilevered thin-walled beams carrying externally mounted stores and exposed to time-dependent external excitations. In this context, and toward this goal, the adaptive materials technology is used. A feedback control law relating the piezoelectrically induced bending moment at the beam tip with the angular velocity at the same point of the structure is considered, and its effects on the closed-loop dynamic response is investigated. The obtained results reveal that this control methodology can play a noticeable role toward confining the oscillations of the considered structure when exposed to blast loadings.
