Vibration analysis of rectangular composite plates in contact with fluid

In this paper, the fluid-structure interaction problem is investigated. In particular, the vibration behavior of a rectangular composite plate in cont act with fluid is studied. The fluid motion is affected by the plate vibrat ion and produces a significant increase of the kinetic energy in the whole system. Therefore, the natural frequencies of the plate in contact with flu id can be determined by calculating the added virtual mass incremental fact or (AVMIF), which represents the increase of the kinetic energy due to the presence of fluid. Once the natural frequencies of the rectangular composit e in contact with fluid have been obtained, the forced Vibration analysis c an be performed readily. In addition, the vibration of the plate in contact with fluid for both simply supported and clamped boundary conditions is in vestigated; meanwhile, the vibration behavior for different plate widths an d lengths is also studied.
