Synergistic implications of tailoring and adaptive materials technology on vibration control of anisotropic thin-walled beams

Abstract

The problems of the mathematical modeling and dynamical response of thin-walled beam cantilevers encompassing a number of non-classical features and incorporating adaptive capabilities are investigated. Whereas the theory of thin-walled beams as considered in this study incorporates the anisotropy of constituent materials, transverse shear and secondary warping, the adaptive capabilities are provided by a system of piezoelectric devices whose sensing and actuating functions are combined and that are bonded or embedded into the host structure. The synergistic implications of the application of both tailoring and collocated sensing–actuating capabilities upon the closed-loop dynamic response of the structure subjected to time-dependent external excitation are revealed, and pertinent conclusions are outlined.
