Prediction of the elasto-plastic post-buckling strength of uniformly compressed plates from the fictitious elastic strain at failure

Original language description

This paper discusses the use of the theory of elasticity to determine the post-buckling strength of uniformly loaded square simply supported thin (steel) plates with sinusoidal-shaped initial imperfections and longitudinal edges free to wave in plane. Based on the findings from a FEM parameter study two main types of failure are distinguished: edge failure and center failure. The parameters determining which failure mode occurs are explained using a simple two-strip model. To determine the elastic post-buckling behavior of plates a modified far post-buckling solution is proposed, which is simpler to use than the existing far post-buckling solutions reported in the literature, giving results with engineering accuracy for loads up to about three times the buckling load. It is shown that determining the post-buckling strength as the elastic load corresponding to first membrane yield (as is done in the effective width method) paradoxically gives reasonable results for plates failing by cen
