[0002] The theory that studies the dynamic properties of the interaction between fluid and solid elastic systems and their application in engineering technology and physics is also called fluid elasticity or hydroelasticity. It and aeroelasticity are both cross-research fields between fluid mechanics and elasticity. In 1956, the 9th International Conference on Applied Mechanics presented a special report on fluid elasticity, which laid a theoretical foundation for the study of hydroelasticity. In the past 30 years, hydroelasticity theory has been widely used to solve hydroelasticity problems in many fields such as water conservancy and hydropower engineering, shipbuilding engineering, marine engineering, petroleum engineering, aerospace engineering, and nuclear engineering.
