What is Wave Impact on Rigid and Flexible Plates about?

Wave impact on offshore and coastal structures, such as oil and gas rigs, offshore wind turbine platforms, breakwaters, flood protection systems and wave energy converters, involve complex wave-structure interactions. These interactions are particularly challenging for flexible structures and may result in structural damage in extreme cases. Some studies found reduced wave forces on flexible compared to rigid walls. However, the technical literature includes inconclusive results on this aspect and an accurate understanding of wave-structure interaction is still lacking. The present study comprehensively investigates wave-structure interaction with the numerical toolbox solids4foam to resolve this shortcoming. The numerical pressures, forces and plate deformations have been successfully validated with new and already available laboratory experiments, e.g. the numerical plate displacement deviates less than 35% from the laboratory observation. 117 two-dimensional (2D) tests of waves impacting plates of different stiffnesses located in the open sea (offshore) and on the coast (onshore) were then conducted, complemented with 2 three-dimensional (3D) tests with offshore plates.
