Abstract
The main purpose of this paper is to assess the implications of a number of effects of geometric and physical nature on the vibration control of adaptive cantilevers modeled as composite thin-walled beams and simulating an aircraft wing. It is considered that the cantilevered beam is exposed to a pressure pulse generated, among others, by a blast or sonic-boom. The features on which preponderance will be given in this study are related with the non-uniformity of the beam cross section in the spanwise direction, anisotropy of constituent materials, transverse shear and warping inhibition. In order to control the dynamic response, a dual approach based on structural tailoring and adaptive materials technology will be implemented. The numerical simulations provide a comprehensive picture of the synergistic implications of the application of both the tailoring technique and feedback control upon the vibration response of nonuniform cantilevers exposed to time-dependent external excitations.
