This manifestation of a localized buckling pattern has been explained in the case of an infinitely long beam (L → ∞) [23] where the shape of the beam is associated to an homoclinic orbit in the corresponding phase space [24].

In this Note the two lowest buckling loads are plotted as a function of the support location and the buckling patterns are studied for different values of the interspan coupling. Webbuckling pattern. These results support the thesis that the circumferential wavenumber n is determined at the pre-buckling stage by the Koiter circle result, and remains flxed until advanced post-buckling. Axial buckling on the other hand is strongly in°uenced by the localization, and soon bears no relation to points on the Koiter circle.
