The multicamerate defence structure of the broadside has great influence on the suvivability of the ship subjected to the underwater contact explosion,and it is important for optimizing and designing new defence structure. In this article,systematic analysis on the damage process of the typical multicamerate defence structure subjected to underwater contact explosion has been done. Mechanisms of different failure modes are revealed,and the relationship between the impact resistance of the multicamerate defence structure,mass detonator and structure thickness is obtained.
