  • In order to study the overall damage characteristics of hull girder subjected to non-contact underwater explosion, a numerical method was established in which an explosive charge was located at the mid-span of the hull girder. The effectiveness of this method was verified by the model test. The damage mode and frequency response were studied to analyze the overall response of the hull girder. Results showed that the numerical method can simulate the response period and amplitude of the hull girder during the first bubble pulsation phase. When the bubble pulsation frequency approximated the first wet frequency of the hull girder, the response mode of girder will transform from whipping motion to sagging with the decrease of the ratio of stand-off to maximum bubble radius.
