Abstract

The buckling of square perforated plates is analysed with the effect of shear deformation in the bending model. The relationship between the buckling load and the plate thickness is better assessed with this bending model instead of the classical model. The simply supported condition at all sides was adopted in the buckling problem such that opposite sides of the plates were uniformly compressed in one direction. The plates had a thickness to length ratio between 1/1000 and 1/5. This study adopted the dual reciprocity method (DRM) to obtain a formulation without domain integrals. The numerical results obtained were compared with those available in the literature.
