Frequencies and Profiles of Standing Flexural-Gravity Waves.

New results of experiments on studying the influence of a floating thin plate on regularization of a standing gravity Faraday wave on the free water surface in a rectangular vessel are given. It is shown that an increase in the thickness of the floating plate significantly affects both the natural frequency of oscillations of the hydroelastic system and the shape of the profiles of the observed standing flexural-gravity waves. When the plate thickness is below the critical value, the waveform is described by the theory of non-linear gravity waves; at large thicknesses, the "dry beam" approximation should be used as approximating dependencies.
