摘要：
As the classic configuration of submarine is like a cylindrical shell, the dynamic responses and damage characteristics of cylindrical shell structures have always been concerned by researchers. The damage caused by underwater explosion load was studied by using double asymptotic approximations method. The plenty analysis of cases, shows that the damage mode can be classified by the cause, such as local strength failure caused by direct impact load, dynamic buckling of local components, circumferential buckling of shell structure, and axial buckling of shell structure caused by whipping responses. Besides, the shock wave and bubble pulsation load are the dominating factors in far and near underwater explosion cases. ©, 2014, Chinese Vibration Engineering Society. All right reserved.
