Resonance effects in propagation of flexural-gravity waves for a supported elastic plate floating on water

We continue our earlier research [1] on propagation of flexural-gravity hydroelastic waves of a small amplitude through a single rectilinear clamp in an elastic plate floating on a fluid of finite depth, where an exact analytical solution was derived. Here, we extend the method to propagation of flexural-gravity waves through a number of parallel rectilinear irregularities having arbitrary spacing. We consider novel types of irregularities in plate. It is shown numerically that the resonant phenomena take place.
