摘　　要：In this paper, the transmitted part of the incident wave is considered to revise Taylor＇s solution, which is used to extend its application for analytical models to predict the response of the plate with different material properties. The influence of the material properties and the boundary condition of the plate on fluid and structural dynamics is systematically investigated. The analytical results are compared with those of detailed dynamic FE simulations and the two are in good agreement. The results indicate that the analytical method is valid and suitable for the plates with different material properties subjected to underwater explosion. It is found that Taylor＇s results of the plate with small impedance are invalid, which indicates a potential application field for the analytical method.In this paper, the transmitted part of the incident wave is considered to revise Taylor＇s solution, which is used to extend its application for analytical models to predict the response of the plate with different material properties.
