This paper discusses the post-buckling behaviour of thin plates under thrust including the secondary buckling phenomenon. A series of elastic large deflection analyses were performed on rectangular plates with various boundary conditions applying the analytical method and finite element analysis. The aspect ratio of the plate is chosen to around 1.0. It was found that: 1) the primary buckling mode of a simply supported rectangular plate is represented by a single deflection component. However, above the primary buckling load, other deflection components also increase with the increase of the compressive load; 2) after the primary buckling, the secondary buckling takes places, os which the deflection mode is three half waves in the loading direction for a simply supported plate and is two half waves for a clamped plate; 3) the inplane rigidity, which is reduced after the primary buckling, is much more reduced after the secondary buckling.
