Buckling of Circular Cylindrical Shells under Beam-Like Bending (2nd Report) Buckling Stress of Cylindrical Shells

摘要

In a preceding paper, the authors have shown by an experiment that the failure of a thin circular cylindrical shell under beam-like bending is attributed to the local bifurcation buckling at the extreme point on the compression side of the bending, rather than the collapse (the limit point buckling) due to the lack of the bending rigidity. The experiment was continued further to measure in detail the pre-buckling deformation of the cross section. The newly acquired results of the experiment are presented in this paper.
