| Abstract: | The shock wave of underwater explosion was simulated in MSC. Dytran, and the results were compared with the ones of empirical equation, showing that this method is responsible. FE analysis of the bilge hold structures under the shock wave of underwater explosion was carried out, to obtain the relation curve of deformation of the model against fullness of dynamite, and the relation curve of deformation against the distance between the model and dynamite. The numerical results tallied with the experiment. |
