Fluid–structure interactions(FSI)which are multi-physics between fluid and structure are a crucial consideration in the design of many engineering systems.Considering the fact that most FSI problems are transient and there are few closeform solutions for the problem,this paper applies normal mode methods to investigate the dynamic transient response of a clamped circular plate subjected to impact loadings in air and coupled with fluid.The method is available for various types of impact loadings such as concentrated force and surface pressure.Considering a small oscillating induced by the plate vibration in fluid,velocity potential function is used to describe the fluid motion.Derivation uses Kirchoffs thin plate theory.To validate the theoretical results,experiments and numerical simulations are carried out.The results are compared with the transient response for displacement,strain,and natural frequencies.Experimental and numerical results are in good agreement with theoretical results.The effects of the height of fluid,impact loadings are investigated.Using this method,the dynamic transient response of plate subjected to an underwater explosion bubble can be solved.
