| Abstract: | For the safety and vitality of a warship,the dynamic response under the action of underwater explosion(UNDEX) shock waves is an important research aspect in the field of ship structural dynamics.In this paper,the dynamic response of a surface warship subjected to UNDEX loading is analyzed with respects to the damage of ship structural deflection,the stress-strain response,the absorption of distortional energy and the impact environment by employing the MSC.DYTRAN code. |
