Modeling of Flexural-Gravity Waves in Ice Cover on Elastic Films

It is noted that, based on observations of fluctuations of the ice cover in natural conditions under the influence of moving loads, i.e., when excitation of flexural gravity waves (FGW), the latter behaves similarly to an elastic isotropic plate.

Description
Summary:It is noted that, based on observations of fluctuations of the ice cover in natural conditions under the influence of moving loads, i.e., when excitation of flexural gravity waves (FGW), the latter behaves similarly to an elastic isotropic plate. On this basis, a new direction has been proposed in modeling some problems of deformation of the FGW ice cover on elastic films in conventional experimental basins. The possibility of this technology is confirmed by the results of comparing records of deformation by moving loads of an elastic model layer and a natural ice cover. Based on the theory of similarity and dimensions, dependencies were obtained for converting model test data to full scale. It is noted that the costs of conducting such model experiments are disproportionately less than the costs of conducting experiments in ice basins. Ice engineering problems are listed, in solving which the developed FGW modeling technique can be used.
