CRITICAL COMBINATIONS OF SHEAR AND LONGITUDINAL DIRECT STRESS FOR LONG PLATES WITH TRANSVERSE CURVATURE
Year: 1947
Abstract: A theoretic solution is presented for the buckling stresses of long plates with transverse curvature loaded in shear and longitudinal direct stress. The theoretical critical-stress combinations for plates having either simply supported or clamped edges are given in figures and tables and a comparison is made with a previous theoretical solution for simply supported plates.
In the compression range theoretical curves are unsuitable for use in design because long plates with substantial curvature loaded in axial compression buckle at stresses that are much less than the theoretical values of critical stress. An investigation was therefore made to determine the modifications required to make the theoretical curves compatible with the available experimental data for plates in axial compression. Interaction curves based upon this investigation are provisionally recommended for use in design. Both theoretical and suggested design curves are essentially parabolas, a circumstance which permits simple approximate interaction formulas to be given.
