Stability of Thick-Walled Elastic Anisotropic 3-Dimensional Cylindrical Shells Under Axial Pressure Load

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.
