Abstract: Within the limits of the exact three-dimensional equations of stability of an equilibrium state of a cylindrical cover with a filler is investigated at axial compression. Calculations were spent for a case when the cover material was modelled by an elastic body, and a filler mate-rial – environment with difficult rheological properties – elastic-viscous-plastic. The estimation of influence on size of critical pressure of parameters of a cover and a filler is given.

Key words: exact three-dimensional equations, stability of balance, cylindrical cover, filler, difficult rheology, axial compression.
