INTRODUCTION: Elastic buckling of cylindrical shells under axial compression is regarded as one of the most difficult tasks involved in the buckling phenomenon. Buckling of a thin-walled shell is typically a local phenomenon that may be triggered by a small, local disturbance. In the case of a very thin shell that exhibits elastic buckling, experimental results show that the first single buckle is initiated at the local portion of the cylinder, the number of buckles sharply increases, and thus the cylinder loses its overall structural stability. In this paper, we trace this successive buckling process using the latest in finite element analysis technology. This paper also describes the generation of singularities in a large-deformed viscoelastic cylindrical shell.
