On vibration suppression of magnetostrictive beams

Laminated composite beams containing magnetostrictive layers are modeled as distributed parameter systems and the magnetostrictive layers are used to control the vibration suppression. Velocity feedback with constant gain distributed controller is chosen to achieve vibration suppression. A general formulation of the problem based on classical and shear deformation (the first-order as well as the third-order) theories is presented, and analytical solutions of the equations are developed for simply supported boundary conditions. The effect of material properties, lamination scheme, and placement of the magnetostrictive layers on vibration suppression is investigated.
