abstract = "In order to explore the dynamic response process of underwater explosion to ice layer, the CEL algorithm is used to establish the underwater explosion-ice layer and bubble-ice dynamic response model to study the dynamic load characteristics of underwater explosion shock wave and bubble,
and the ice under the corresponding load. Layer dynamic response and damage characteristics. The results show that the shock wave load is higher than the bubble load, but the load pulse width is lower; the damage to the ice layer during the explosion shock wave stage can be divided into the
ice free surface tensile failure caused by the stress wave unloading, and The impact surface collapse due to excessive shock wave failure. The bubble stage damage can be divided into the failure of the ice layer free surface caused by the bubble burst shock wave and the jet, and the penetration
failure of the burst surface. The shock wave phase is the main stage of ice damage, and the back damage surface tensile damage is the main form of ice material damage. The bubble stage is the secondary stage of ice damage, and the impact surface penetration damage is a secondary form of ice
material damage.",
