| Abstract: | It is known that plates are not sensitive to initial imperfections, since, after buckling, their load deformation curve is upwards. Flat rings on circular cylinders are circular ring plates. Therefore, their postbuckling behavior is the same. This is proved theoretically in this paper. Hence, it follows that the slenderness of flat rings is not restricted by stability considerations, in contrast to the ECCS and BS 5500 recommendations. |
