Abstract : Several investigators have presented results which indicate that the disagreement between experimental collapse loads and buckling loads predicted by classical small-deflection theory for axially compressed thin-walled circular cylinders can be adequately explained with the use of approximate large-deflection energy analyses. The snap-through manner of collapse is explained by the fact that finite-deflection equilibrium configurations exist for loads or strains considerably lower than those predicted by classical theory. Recently, several investigators have applied similar large-deflection analyses in search of an explanation of the discrepancy between experiment and classical theory for cylinders under external hydrostatic pressure. In the present notes a summary is given of results of large-deflection analyses of homogeneous, isotropic cylinders under axial compression and under hydrostatic pressure, the effect of asymmetric and axially symmetric initial deformations on the load-deflection characteristics of hydrostatically loaded shells is determined.
