In recent years, the primary concern in naval engineering and offshore structure research is predicting how submerged structures are damaged by underwater explosion (UNDEX). Ascoustic-Structure Coupling (ASC) and Coupled Eulerian-Lagrangian (CEL) method were used to replicate experimental test of K.Ramajeyathilagam (2004). This study developed two procedures to investigate the response of a thin rectangular plate subjected to UNDEX by using ASC and CEL method. Numerical analysis for the experimental model was performed the propagation of the shock wave and the bubble pulse of an UNDEX. Simulation results of two methods were shown to identify the effective of shock and bubble pulse by using ASC and CEL method. All of these results can be a valuable reference to the research of underwater explosion.
