“…And solving the problem of damping vibrations of structural elements under stationary and non-stationary conditions for various purposes depends on the composition of the composite material [6,7]. To study the damping of resonant vibrations of a panel during the snapping process, viscoelastic components of polymer particles with high energy losses are introduced into its structure [8,9]. Depending on the type of anisotropy of the material and inclusions, as well as the geometric configuration of the inclusions, the panel material can be viscoelastic isotropic, nano-transversally isotropic or orthotropic.…”

The paper considers the dynamics of the process of a flat rectangular elastic panel having an initial deflection equal to the critical deflection of the static problem of panel stability. The panel is loaded with compressed gas enclosed in a small volume container. Using this value, the load acting on the panel during the snapping process will depend on the deflection of the panel as a result of the adiabatic expansion of the compressed gas. The main goal of the work is to investigate the stability region of a cylindrical panel when loaded with compressed gas. The problem is solved using a developed methodology based on the method of separating variable equations of mathematical physics. Based on calculations, it was found that when the panel is loaded with compressed gas enclosed in a small-volume container, a stabilizing effect appears, i.e. a certain deflection interval appears where the panel does not lose stability. The presence of external pressure makes it possible to expand this area, i.e. the external environment increases the “stabilizing” effect. Also, taking into account the viscoelastic properties of the material expands this area to 10%.
