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 Sp(=p/pk) and Sx(=σθK,θ). These results were then compared with the predictions of the linear interaction equation Sp + Sx = 1 and two nonlinear ones. The minimum predicted buckling quantities pk 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.
