Abstract

The elasto-plastic buckling of perforated plates under uniaxial compression was investigated. The finite element method (FEM) was used to determine the buckling load in the plates. The inelastic behavior of rectangular perforated plates with aspect ratio of 2, was also studied. It was found that the critical buckling stress for perforated plates decreased as the plate slenderness ratio increased, and the decrease became steeper for large values of plate slenderness ratio. It was also observed that critical stress decreased as the hole size increased, and their value depend on the yield point of the steel used.
