Abstract
Perforated plates are widely used in aerospace and structural engineering where the cut-outs serve as a means of weight reduction, give aesthetic appeal or assist in cooling purposes. By selecting the proper cut-out shape better mechanical properties can be obtained for the same amount of material removed. In this study, a buckling analysis was carried out on stainless-steel plates with and without perforation by using finite element method. Stainless-steel plates having constant width and thickness with varying lengths were analysed to examine the impact of length on buckling load. Plates of constant length and width, with varying thickness were analysed to examine the impact of thickness on buckling load. Plates of constant length and width having diamond-shaped perforation of seven different sizes were analysed to examine the impact of perforation size on the buckling load values. And plates of constant length and width having a diamond-shaped perforation with seven different orientations with the horizontal were analysed to examine the impact of perforation orientation on buckling load. ANSYS 19.2 software was used to perform the finite element analysis.
