Wave-structure interaction is an academic concept and field of study concerned with the dynamic processes that occur when propagating waves encounter and interact with physical structures. It investigates the reciprocal influences, including the forces exerted by waves on structures, the resulting structural response (deformation, motion, stress), and the potential modification of the wave field by the structure's presence and response. This research area is fundamental for the analysis, design, and performance assessment of structures subjected to dynamic wave loading in various physical domains, such as hydrodynamics, acoustics, seismology, and aeroelasticity.
