Buckling of Circular Cylindrical Shell under Beam-like Bending (1st Report) Experiment

摘要

This paper presents the results of an experimental study on the buckling of circular cylindrical shells under beam-like pure bending. In the experiment, emphasis was placed on the effect of the length of the cylinder. A high precision loading instrument was developed, by which the torque can be applied equally on both ends of the cylinder. Test specimens have a length-to-diameter ratio ranging from 1 to 20 and a diameter-to-thickness ratio of 156, 200, 234, or 300. Large deformation accompanied by a flattening of the cross section was observed before buckling in long cylinders.
