Abstract
In general, laminated composite cylindrical shells exhibit the effect of lamination constitution due to the anisotropy and the unsymmetry of lamination. In the present paper, the buckling problems of carbon fiber/epoxy (CFRP) cross-ply and angle-ply laminated cylindrical shells under torsion are considered. That is, the effects of stacking sequence, number of layers, lamination angle, buckling modes and dimension of cylinders, on the buckling stresses are analysed by use of the equilibrium equation based on the Donnell-type expressions.
