Abstract: This paper examines the relationship between thin (Kirchhoff) and thick (Mindlin) plate buckling solutions for constant thickness plates under isotropic inplane compressive loads. The two solutions have been found to be linked by a factor, which is referred to as the shear effect factor. This factor is dependent on the thin plate solution, the plate thickness, shear modulus and the shear correction factor (which arises from the Reissner-Mindlin first order shear deformation assumption). The shear effect factor is exact for simply supported and clamped circular plates and simply supported rectangular plates. From comparison studies, it appears that it may also be exact for arbitrarily shaped plates with all edges simply supported. The factor has been found to predict the buckling solution for thick plates with combinations of simply supported and clamped edges to within a maximum error of about 3%-4%.
