| dc.description.abstract | In this study, a complete theoretical formulation of laminated composite plates with integrated smart material layers that serve as sensors and/or actuators is presented for the vibration suppression of laminated composite plates. The third-order shear deformation theory of Reddy is used to represent the structural behavior. The smart material layers are used to control and enhance the vibration suppression of the plate through a simple velocity feedback with a constant gain control. As an example Terfenol-D particle sheets (a magnetostrictive material) are used to suppress vibration. Analytical solutions of the governing equations are obtained for rectangular laminated plates with simply supported boundary conditions. The displacement finite element model of the general formulation is also developed, and solutions for simply supported as well as clamped boundary conditions are obtained. The effects of material properties, position of smart material layers, lamination scheme, thickness of the laminae and the feedback coefficient on the vibration suppression characteristics of the laminated composite plates are studied. The results obtained show that better vibration suppression is obtained when (1) the smart material layer is farthest from the neutral axis, (2) thinner smart material layers are used, and (3) the mode number of vibration increases. Possible extensions of this current work are also discussed. | en |
