Abstract:Coated plates are widely used in naval ship structure for better protection from underwater explosion. Further understanding of wave propagation mechanism in multilayered mediums is very significant. A second-order Godunov method is used to establish the calculation model for wave propagation mechanism in the coating plate subjected to underwater explosion. The numerical results are in good agreement with Taylor’s solution. Different boundary condition and thinness of the coated plate are analyzed to obtain the effects on the coated plates. The results offered a reference for designing and studying submarine's shock resistance.
