Abstract
The motion of a flexible elastic plate under wave action is simulated, and the well–known phenomena of overwash is investigated. The fluid motion is modelled by smoothed particle hydrodynamics, a mesh-free solution method which, while computationally demanding, is flexible and able to simulate complex fluid flows. The freely floating plate is modelled using linear thin plate elasticity plus the nonlinear rigid body motions. This assumption limits the elastic plate motion to be small but is valid for many cases both in geophysics and in the laboratory. The principal conclusion is that the inclusion of flexural motion causes significantly less overwash than that which occurs for a rigid plate.
Highlights
The interaction of a flexible floating plate with wave forcing has been the subject of extensive research due to the application in offshore engineering, polar engineering, and geophysics [1,2,3,4].The general assumption is that the wave amplitude is small enough that the problem may be treated as linear
One of the earliest work on the application of Smoothed particle hydrodynamics (SPH) to simulate water wave breaking on a beach, overwashing a flat plate, and from a dam break is due to Dalrymple and Rogers [32]
The results reveal that the elastic bending of the plate has a specific role in reducing the overwash since it partly absorbs the kinetic energy of the incident waves
Summary
The interaction of a flexible floating plate with wave forcing has been the subject of extensive research due to the application in offshore engineering, polar engineering, and geophysics [1,2,3,4]. One of the earliest work on the application of SPH to simulate water wave breaking on a beach, overwashing a flat plate, and from a dam break is due to Dalrymple and Rogers [32]. It is just a phenomenological study, this study highlighted the potential of SPH for challenging multiphase problems. Our study has application to the storm damage of very large floating structures and the melting and breakup of sea ice. our focus here is on simulating at the laboratory scale where extensive experiments have been conducted.
