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. how much are home inspections in texas
