The stability of elastoplastic shells under proportial subcritical processes of combine loading
The problem of bifurcation of thin-walled cylindrical shell under proportional subcritical loading by axial compressing force, torque and internal stress in the deviatoric space by A. A. Ilyushin's strain was investigated. The relationship of stress and strain is adopted in accordance with the defining relations of the above-mentioned hypothesis. For determinative functions of plasticity there were used approximations, which were offered by V. G. Zubchaninov.
