This article examines the impact of boundary conditions on the buckling load for rectangular uniform isotropic plates of different aspect ratios and cut-out shapes. Plates with cut-outs have been extensively used in many applications like an aircraft fuselage, wings, etc. So proper understanding of their buckling is a crucial step before implementing them in various applications. Tests have been completed on aluminium alloy plates with circular holes and notches under different boundary conditions comprising of clamped, fixed and their combinations are considered. For complex geometries like such, analytical methods are tiresome and time-consuming, hence numerical methods are enforced to obtain very close results to what is expected from an analytical solution. Analysis by the numerical method is led and the effect of aspect ratio, boundary conditions, and cut-out shape on the buckling behaviour of isotropic plates under in-plane axial compression load is investigated and discussed. Buckling analysis is performed by employing finite element analysis software ANSYS. The numerical results received are in true agreement with the formerly posted data.
