| Abstract: | A three-dimensional finite element model of a whole ship was established to simulate numerically the dynamic responses of the overall ship under underwater explosion.In this way,the damage mode of the main structure was deeply discussed and the influence of the ship whipping to the ship longitudinal strength was analyzed as well.The damage mode and rules of the whole ship in shock wave phase and bubble impulse phase were summarized. |

| Keywords: | overall ship shock wave bubble impulse failure mode |
