Static Buckling and Postbuckling Characteristics of Thin-Wall Aluminum Cylinders under Eccentric Compressive Axial Loads

摘要

Results from experimental measurements of buckling threshold and postbuckling characteristics of thin-wall aluminum-alloy circular cylinders loaded at various fixed ratios of axial compressive load to applied bending moment are reported. Buckling modes, both symmetric and antisymmetric, with respect to the plane of loading occurred and are presented. Typical results are shown. Postbuckling measurements of load-deflection characteristics are extended to very large deflections, and include a number of measurements during unloading and reversed loading. (Author)
