Paper Abstract

The problems of the mathematical modeling and dynamical response of thin-walled beam structures including a number of non-classical features and incorporating adaptive capabilities are considered. The theory of thin-walled beams as considered in this study encompasses non-classical features such as anisotropy, transverse shear and secondary warping, whereas the adaptive capabilities are provided by a system of piezoelectric devices whose sensing and actuating functions are combined and which 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 are presented and pertinent conclusions are outlined.
