| Abstract: | An improved DAA method is developed to predict the dynamic response of suspending shell to underwater shock. The equivalent energy and equivalent depth is introduced to compute the dynamic characteristics of moving and pulsing bubble in water. The numerical computation is compared with the experimental data, and the experimental pressure for mula of pulsing bubble when a cylinder is suspended into water is proposed. |
