| Abstract: | In the paper, a numerical analysis by long-distance loading method in MSC Dytran to simulate the damage of a hull structure subjected to shock waves reflected on free surface is proposed. The hull structure damage is obtained by this method. Comparison with the expriment proved the reliability of this method. |
