In the post-buckling analysis of axially compressed thin-walled cylindrical shells, we can use two kinds of strain-displacement relation, i.e. Donnell type and Flugge type. Former is relatively simple, but is not so correct (due to shallow assumption) when a shell becomes long. In this study, the Flugge type is employed and more accurate euilibrium paths in the post-buckling region are traced numerically. In order to estimate the snapping or bifurcated paths, the energetic evaluation is also applied.
