Frontiers Plastic Buckling Paradox: An Updated Review

WebHe suggested that the plastic buckling load obtained by the tangent-modulus theory could be considered the lowest load at which a straight column remained stable and it should be therefore considered as the actual buckling load. The ratio of the effective length of a column to the least radius of gyration of its cross section is called the slenderness ratio (sometimes expressed with the Greek letter lambda, λ). This ratio affords a means of classifying columns and their failure mode. The slenderness ratio is important for design considerations. All the following are approximate values used for convenience.
