The objective of this paper is to examine and clarify the fundamental post-buckling behavior including elasto-plastic collapse of circular cylinder subjected to axial loading. A series of elastic and elasto-plastic large deflection analyses as well as elastic eigen buckling analysis are performed. On the basis of the numerical results, the effects of curvature (R/t), magnitude of initial imperfection on the characteristics of the post buckling and collapse behavior of circular cylinder under design loads are discussed. The obtained critical buckling stress will be compared with the theoretical formulations of Timoshenko.
