On Design Procedures for the Buckling of Cylinders Under Combined Axial Compression and External Pressure

Abstract

The test results on biaxially compressed metallic cylinders published before 1983, together with some early ones from a test program underway at Liverpool University, were plotted in terms of the stress ratios S p (=p /p k ) and S x (=σθ /σK ,θ ). These results were then compared with the predictions of the linear interaction equation S p + S x = 1 and two nonlinear ones. The minimum predicted buckling quantities p k and σk ,x were evaluated using the recommendations of ASME III N-284, DASt, DnV and ECCS. Based on this study, some possible design procedures for this interactive buckling problem are suggested.
