我们考虑充液管对内部激波和爆炸的响应。重点是流固耦合方面。流体中的轴向波传播与管中的弯曲波的耦合可以用单个参数来表征，该参数仅取决于管和流体材料的性质和尺寸。用该参数作为优值，讨论了流体波动与管状结构运动弱耦合和强耦合的极限情况。讨论的例子包括在金属、聚合物和复合材料的气体和液体填充管中的爆炸和冲击波。给出了弹性变形和塑性变形的实验结果以及断裂和破裂的部分结果。充气管的爆轰通常处于弱耦合状态，除了非常薄的管或变形导致管破裂的情况。在充满液体的管道中，冲击产生的轴向波可以从弱到强的耦合情况，这取决于管壁厚度和材料。这些例子包括众所周知的水锤现象，我们描述了冲击研究与以前关于水管道中波传播的工作的关系。
We consider the response of fluid-filled tubes to internal shock waves and explosions. The emphasis is on the fluid–solid coupling aspects. The coupling of axial wave propagation in the fluid to flexural waves in the tube may be characterized by a single parameter that depends only on the tube and fluid material properties and dimensions. Using this parameter as a figure of merit, we discuss the limiting cases of weak and strong coupling between the fluid wave motion and tube structural motion. Examples discussed include detonation and shock waves in gas and liquid-filled tubes of metal, polymers, and composites. The results of experiments on elastic and plastic deformation are presented as well as selected results on fracture and rupture. Detonation in gas-filled tubes usually falls in the weak coupling regime except for very thin tubes or cases of deformation that lead to tube rupture. Impact generated axial waves in liquid-filled tubes can range from weak-to-strong coupling cases depending on the tube wall thickness and material. These cases include the well-known phenomenon of water hammer and we describe the relationship of impact studies to previous work on wave-propagation in water-filled pipes.
