Definition
Hydroelasticity was first defined by Heller and Abramson (1959), who stated that “it is concerned with the phenomena involving mutual interactions among inertial, hydrodynamic and elastic forces.” Theoretically, the fluid pressure acting on a structure will cause rigid body motion and structural deformation, and rigid body motion and structural deformation will interfere with the surrounding flow field. Hence, fluid-structure interaction problems can be considered hydroelastic problems. However, compared with rigid body motion, the deformation of traditional offshore structures, such as ships and platforms, is very small. The influence of deformation on the flow field can be ignored. Thus, when calculating the surface pressure, the structure can be regarded as a rigid body. According to structural analysis, the structure is regarded as a deformable body, and structural...
