“…Carnoy et al (1984) proposed an exact representation of the load stiffness functional derived from the pressure load potential corresponding to the follower force, and performed the buckling analysis of the curved surface structures under pressure load by using the isoparametric volume element and the thin shell, and the thick shell elements. Song and Tassoulas (1994) predicted the propagation pressure in the submarine pipeline, and observed the buckling phenomenon for long cylindrical tubes under external pressure by using beam element. In addition, Toscano et al (2008) developed the finite element model discretized with shell elements for analyzing the buckling and buckling propagation of stiffened pipes, and verified the developed model by comparing the numerical results obtained using it with the experimental data.…”

This paper presents a numerical procedure using shell element to evaluate the buckling behavior of the cylindrical structure subjected to pressure load. In numerical simulation for pressure vessels using conventional shell elements, the pressure loads imposed to both top and bottom surfaces are expressed as the difference between the internal and external pressures. In this work, the special shell element, in which the surface traction is exactly expressed at the surface, is applied to the buckling analysis. In this approach, the distribution of the transverse normal stress through the thickness can be evaluated. Therefore, the influence of the difference between the internal and the external pressures to the behavior of the buckling of the cylindrical shell structures can be assessed. In the situation that a perturbative load is applied under a certain stress state, bifurcation points are searched by solving a standard eigenvalue problem. Several numerical examples are presented to examine the effectiveness of the proposed approach. The buckling behavior that cannot be considered with the conventional shell elements can be observed by this approach.
