Magnetorheological (MR) materials indicate variations in their rheological properties when subjected to different magnetic fields. This study presents vibration analysis of laminated composite plates using MR fluid lumps. A structural dynamic modeling approach is presented to investigate the vibration characteristics of MR adaptive structures for different magnetic fields. The effects of laminate configurations and locations of MR fluid lamps on the controlled response are investigated. Vibration responses of the laminated plate have been simulated to demonstrate the accuracy and efficiency of the present approach. The results of this work may improve the dynamic performance of composite structures which are subjected to undesirable vibration during operation such as helicopters blades
