Buckling and Failure Strength of Plating Panels Loaded in Shear. Part I. Tests of Unstiffened Panels

摘要

Panel specimens were fabricated from four materials: Low carbon steel, COR-TEN, AISI 4130 normalized, and 2024-T3 aluminum. The test panels were either 6 x 30 or 12 x 60 inches in net section, and varied in thickness from .070 to .200 inch. Width to thickness ratios varied from 30 to 160. The specimens were clamped on the long edges and loaded in pairs by means of a shear test frame. Lateral deflection, surface strains, and shear deformation were recorded during the test. Preliminary analysis of the results indicates that use of the strain reversal method for determining critical buckling loads resulted in critical stresses less than predicted by theory. However, this method of determining the critical loads was felt to be dependable and realistic in terms of panel behavior. The data on buckling and failure were consistent, both within a given class of material and for all materials as a group. (Author)
