“…Paslara 7 investigated infill plate boundary condition effects by FEM on the overall performance of steel plates with circular openings. And Loughlan 8 adopted finite element modelling strategies and solutions procedures to enable the determination of post-buckling failure responses of steel plates with cutouts. More studies were seen on the elastic buckling behaviour of rectangular plates with cutouts for partial edge loading, 9 the elastoplastic buckling behaviour of simply supported rectangular plates with elliptic cutouts 10 and the post-buckling behaviour of thin plates with central circular cutouts subjected to biaxial load 11 using FEM.…”

Perforated plates are widely used in thin-walled engineering structures, for example, for lightweight designs of structures and access for installation. For the purpose of analysis, such perforated plates with two opposite free edges might be considered as a series of successive Timoshenko beams. A new semi-analytical model was developed in this study using the Timoshenko shear beam theory for the critical buckling load of perforated plates, with the characteristic equations derived. Results of the proposed modelling were compared with those obtained by FEM and show good agreement. The influence of the dividing number of the successive beams on the accuracy of the critical buckling load was studied with respect to various boundary conditions. And the effect of geometrical parameters, such as the aspect ratio, the thickness-to-width ratio and the cutout-to-width ratio were also investigated. The study shows that the proposed semi-analytical model can be used for buckling analysis of a perforated plate with opposite free edges with the capacity to consider the shear effect in thick plates.

“…Loughlan and Hussain 21 used PATRAN/NASTRAN finite element commercial software to analyze the critical buckling load and elastoplastic postbuckling behavior of perforated steel plate under in-plane shear displacement. To define the nonlinearity material, an elastic-perfect plastic hardening model was considered.…”

This article investigates the elastoplastic response of buckling and postbuckling behavior of plates under uniaxial and biaxial end-shortening considering incremental theory and deformation theory of plasticity. According to elastoplastic buckling and postbuckling behavior of plates, the finite element code considering geometrically and material nonlinearities is developed based on incremental theory and deformation theory of plasticity. The results show that boundary conditions, loading ratios, and aspect ratios of a plate have a significant effect on the discrepancy between incremental theory and deformation theory. Moreover, differences in estimating the buckling point using incremental theory and deformation theory are less than 10%, while in a number of plates at the last loading steps, postbuckling paths determined by incremental theory and deformation theory are diverted from each other. Also the difference between these two theories in the postbuckling region is more noticeable by increasing the thickness of plates.
