| Abstract |
Using the simplest hydroelastic system as an example, we study the mutual influence of the buckling of an elastic plate under a compressing force and the deviations of the contact interface between fluids of distinct densities. The system is in an acceleration field perpendicular to the contact interface between the media. Depending on the compressing force variation law, the problem is considered in either the linear static or the dynamic statement. The prevailing formation of short waves in the plate under dynamic loading is taken into account. The cases of absence of the action of a compressing force on the plate and of its contact with the fluid, of equal densities of the two fluids, and of their small influence on the system dynamics, as well as the influence of the distribution of the initial plate deflection over the harmonics on the system dynamics, in particular, mode rearrangement in the buckling process, are studied. |
