Title: Dynamic Response of Air-backed Plate Under Underwater Explosion
Abstract: In order to study the load bearing capacity of the grillage under underwater explosion,the dynamic response of the air-backed clamped square plate under the underwater explosion shock loading was analyzed numerically.The influence of shock factor on the final deformation of plate had been studied.Effect of strain rate and the changing of air pressure on the plate dynamic response behavior were discussed.The numerical results were basically consistent with the experimental results.The results indicated that the bigger the impact factor is,the bigger is the displacement of the plate center.So that the effects of strain rate must take into account,but may not consider the changing of air pressure influence.
