A Review of Research on Action Mechanism and Damage Effect of Underwater Explosion

To further reveal the action mechanism and damage effect characteristics of underwater explosion,the progresses of study on the action mechanism and damage effect of underwater explosion were systematically reviewed from six aspects as mechanism,shock wave propagation,bubble pulsation,damage effect and dynamic response of structure,test technology and numerical simulation and damage assessment for underwater explosion of different explosives.Some key technical problems which should be investigated or solved in future including energy release and diffusion of the underwater explosion of non-ideal explosive,damage of coupling action of shock wave and air bubble to structure and damage assessment methods for underwater explosion,multi-scale simulation technology for underwater explosion were proposed with 86 references.
