The Mathematical Model

The mathematical model of the stability analysis of circular cylindrical shells under arbitrary internal pressure is presented. The paper consists of a direct analysis of the equilibrium modes in the neighbourhood of the unperturbed principal equilibrium path. The final stability condition results in a completely symmetric differential operator which is then compared with current theories found in the literature.

Laminated Cylindrical Shells

The linear bending theory of laminated elastic cylindrical shells under axisymmetric loading is developed from first principles. It is shown that a spontaneous “beam-column” type of deformation may develop even in the absence of end loads. Generally, however, this effect is shown to be small for metallic cylinders, in which case the laminated shell deforms in the same manner as a homogeneous shell, where the effective flexural rigidity and effective extensional rigidity are both shown to have a simple dependence upon the “elasticity distribution” throughout the wall thickness. The influence of edge loads on a pressurized semi-infinite shell are determined and applied to find the stresses in a titanium shell with a steel reinforcing band.

This paper deals with the initial postbuckling of antisymmetric cross-ply closed cylindrical shells under torsion. Under the assumptions employed in Koiter’s theory of elastic stability, the structure is imperfection-sensitive in certain intermediate ranges of the reduced-Batdorf parameter (approx. 4 ≤ ZH ≤ 20.0). Due to different material bending-stretching coupling behavior, the (0 deg inside, 90 deg outside) two-layer clamped cylinder is less imperfection sensitive than the (90 deg inside, 0 deg outside) configuration. The increase in torsional buckling load due to a higher value of Young’s moduli ratio is not necessarily accompanied by a higher degree of imperfection-sensitivity. The paper is the first to consider imperfection shape to be identical to the torsional buckling mode and presents concise parameter variations involving the reduced-Batdorf paramter and Young’s moduli ratio.
