A finite element formulation of solving the stability problems for composite cylindrical shells is presented, taking into account the momentness and nonlinearity of their subcritical stress-strain state. The stability of a circular cylindrical shell made of a polymer composite material under combined loading by torsion and bending moments is investigated. The influence of the methods of laying monolayers, the nonlinearity of deformation on the critical loads of the shell stability loss and the weight efficiency of composite shells in comparison with metallic ones is clarified.
