Solution of the problem of bifurcation of a cylindrical shell considering the complex nature of deformation at the time of loss of stability under complex loading

The authors consider the problem of bifurcation of a thin-walled circular cylindrical shell taking into account the complex nature of the deformation at the time of loss of stability under complex loading by sub-critical axial compressive force and torque in the deviatoric A. Ilyushin plane of strains.
