NUMERICAL STUDY ON THE INTERACTION BETWEEN PERIODIC WAVES AND A FLEXIBLE WALL

Coastal structures were usually considered as stiff in the majority of studies related to wave structure interaction I n certain situations, such impulsive loading on flexible breakwaters, ship hulls, tank walls hydroelasticity can be importance for both dynamics and structural responses Akrish et al. (2018) showed that hydroelastic effects either relax or amplify hydrodynamic characteristics (i.e., run up force) oscillations a deformable cantilever wal l interacting with an incident group. For coastal defenses, Huang Li (2022) elastic horizontal plate breakwater exhibit better performance damping than rigid one. Sree (2021) experimentally investigated submerged viscoelastic under surface waves. They reported complete cutoff energy plate. However, steep fronted nonlinear progressive waves was not yet studied de tailed manner , which requires advanced numerical methods modelling between fluid solid finite deformations. The present study focus es behavior vertical wall periodic different periods (or frequencies )). stiffness evolution deformation are fully coupled model.
