| Abstract: | A general analytic method is presented for the evaluation of the elastic buckling of cylindrical shells and panels with longitudinal stiffening under hydrostatic pressure. An accurate solution is obtained through direct solution in which shallow shell equations are used. The effect of the distance between stringers and size of stringers on elastic buckling are discussed. The numerical results obtained are compared with analytic and experimental ones given by other investigators. It is shown that the method proposed is fairly accurate. |
