## Interaction of Underwater Explosion Bubble With Complex Elastic-Plastic Structure

• 摘要: 计及结构的弹塑性，将边界元法(BEM)与有限元法(FEM)耦合提出了气泡与弹塑性结构耦合动力学计算方法，并开发了全套的三维水下气泡分析程序（UBA），计算值与实验值之间误差在10%以内．以水面舰船为例，将三维计算程序工程化．并分析了水下爆炸气泡载荷作用下船体的弹塑性响应，从船体结构典型单元上的应力时历曲线可以看出，在气泡坍塌时出现应力峰值，证实了气泡坍塌压力及射流引起的压力对舰船等结构造成严重毁伤．从气泡与舰船的相互作用中可以看出，舰船低阶垂向振型被激起，在气泡作用下呈鞭状运动，同时舰船随着气泡的膨胀和收缩作升沉运动，通过本文的分析得到了适合于工程应用的规律及结论．
