Abstract

Abstract

In this paper, Neale's generalized variational principle about incremental boundary-value problems is utilized to study the effect of initial imperfections in geometry on the critical loads of elastic-plastic buckling of thin annular plates. The calculations show that, if the effect of initial imperfections in geometry is taken into account in the solutions by J₂ incremental theory, the results are very close to the bifurca-tional buckling loads of the perfect annular plates according to the plastic deformation theory.
