Abstract

The consider dynamical stability problems for a closed, medium-filled cylindrical shell simply supported by end faces and strengthened by a cross system of ribs, under axial compression and uniform external pressure. The formula for defining critical time and the values of critical stresses corresponding to the found critical time under the action of step impuls and for linear law of decrees of suddenly applied load are found.

Keywords

Dynamical stability, cylindrical shell, cross system of ribs, axial compression, external pressure
