Abstract
By analyzing, as an example, a thin elastic rectangular plate streamlined by supersonic gas flows, we study the loss stability phenomenon of the overrunning of the gas flow at is free edge under the assumption of presence of compressed forces at the free und hinged edges. Critical velocities of divergence of the panel and localized divergence are found. It is established that the compressed forces leads to the destabilizing of unperturbed equilibrium state of a plate in supersonic gas flow.

Steady-State Vibrations Of Elastic Space Contaning Elastic Infinite Strip
The problem of steady-state vibrations of elastic space contaning elastic infinite strip under the action of a linear source of harmonic vibrations is considered. The problem is solved with the aid of Fourier integral tr...
