BUCKLING CHARACTERISTICS OF CORRUGATED CYLINDERS - EFFECT OF USING A HIGH STRENGTH MATERIAL.

Abstract

Results of a supplement to an investigation to study the buckling characteristics of corrugated cylinders are given. The present study evaluates the effect of using a high strength material. Twenty-five models of varying height, fabricated from 7075-T6 aluminum, were tested under axial compressive loads for instability. As in the earlier work, the buckling of corrugated cylinders is treated from the viewpoint of the buckling of individual corrugation elements. For slenderness ratios of these elements greater than 110, the buckling data correlate satisfactorily with the Euler column theory. For slenderness ratios below 82, the critical stress is much lower than that predicted by any of the column theories and is approximated closest by the elastic plate buckling criterion which serves as an upper limit.
