    Abstract
  • In order to study the damage effect of ship structure subjected to jet impacting, characteristic of jet loading was investigated theoretically and numerically. A jet impact-model was verified based on a ship cabin model underwater explosion test. An analysis was made by combining the calculation results and test data. Results show that the jet impact can induce a strong local response on the structure. Under certain circumstance, jet impacting response is more severe than that caused by shock wave even when bubble incepts at a relatively far position. Therefore, jet impact problem cannot be considered only in proximal underwater explosion test. The jet impact-model developed in this work could reflect the loading feature accurately, and would provide reference to underwater explosion experimental analysis.
