On the basis of the refined Timoshenko-Mindlin beam theory,an approach to calculate the stability of three-dimensional anisotropic cylindrical shells of geometrically nonlinear subcritical stress-strain state,in which the extreme layers are of higher rigidity than the average,is presented.The shell material has symmetry properties in a plane that could match the median surface.Numerical solutions are performed with the use of discrete orthogonalization methods.In the paper the plots illustrating the influence of stacking sequence and lay-up angle of layered fibrous composites on magnitude of critical values of axial compression are presented.
