Ships, ship-shaped offshore structures, land-based structures and aerospace structures typically consist of various curved plate components. It is difficult to simulate the buckling and post-buckling of curved thin and/or thick plates that have characteristics of nonlinear structural mechanics, such as nonlinear behaviour when loading is applied. The elastic post-buckling behaviour of a curved plate is very complex, and accompanied by mode changes due to the occurrence of secondary buckling behaviour. Therefore, it is very important to clarify the elastic post-buckling behaviour when subjected to axial loading. The aim of this study was to derive an analytical calculation based on the formulation of the total potential energy, and a mathematical solution to simulate the elastic buckling and post-buckling behaviour of cylindrically curved plates under axial compression. The accuracy of the proposed method with the aforementioned modelling techniques was verified through comparison with finite element analyses of various curved plate configurations.
