Abstract
Vibration reduction possibilities in laminated composite with one of the plies as actuation layer, have been investigated. Magnetostrictive and piezoelectric actuation have been considered. A comparative assessment of the vibration suppression performance of piezoelectric and magnetostrictive actuation in laminated composite beam has been presented. Variation of closed loop frequencies and damping coefficients with respect to the changes in ply lay- up, active layer position and controller gain have been studied. A smart composite finite element for laminated beam analysis has been developed. Numerical results have been presented in typical cases, to indicate performance of the finite elements developed and also to indicate the variation of vibration reduction times with various geometric and control parameters.
