Elasto-plastic analysis for the buckling and postbuckling of rectangular plates under uniaxial compression (original) (raw)

Full-range analysis for the buckling and postbuckhng of rectangular plates under inplane compresswn has been made by perturbation techmque which takes deflection as [td perturbatton parameter. In ttus paper the effects of inttial geometric imperfectton on the postbuckling behavior of plates have been dtscussed. It is seen that the effect of intttal imperfectton on the melastw postbuckhng of plates is sensittve. By comparison, tt is found that the theoretical results of thts paper are in good agreement wtth expertments.
