| Abstract: | For the safety and vitality of a warship, the dynamic response under the action of under-water explosion (UNDEX) shock waves is an important research aspect in the field of ship struc-tural dynamics.In this paper, the dynamic response of a surface warship subjected to UNDEX load-ing is analyzed with respect to the damage of ship structural deflection,the absorption of distortion-al energy and the impact environment by employing the numerical method. |
