Description:
Considering a simply supported plate under uni-axial compression it is well-known that after buckling the stress concentrates at the unloaded boundaries as the out-of-plane displacement at the buckle causes an in-plane relaxation, i.e. a decrease of the mid-plane stress. This stress distortion is described by the so-called effective width. The knowledge of the effective width allows the calculation of the stress at the unloaded boundaries, which is usually considered as the highest stress in the plate. However, the out-of-plane displacement also bends the plate, which produces additional stresses. This article analysis the fundamental question, if the total stress at the surface of the buckle is higher than the stress at the unloaded boundaries. (© 2011 Wiley-VCH Verlag GmbH & Co.
