N2 - A thin shell tube with different length to radius and radius to thickness ratios can buckle locally, globally or with interaction of local and global buckling. The current analysis is to study the dependency of the buckling load of a circular cylindrical shell on these ratios. Different theoretical shell models were used to predict the buckling load and the results were compared with finite element analysis. It was found that the buckling load decreases exponentially when the length to radius ratio increases and increases when the radius to thickness ratio increases. The length to radius ratio is crucial in determining whether the tube is in the local buckling, global buckling or interaction region. The extent of global buckling was predicted analytically using Sanders' model, and was found to depend on the Poisson's ratio of the material used. In addition, Loo's model is found to be the best model in predicting the buckling load in the local buckling and interaction region to within 10% of the finite element results while the Sanders' model converges to Euler buckling values in the global buckling region.
