Effect of Curvature on Strength of Axially Loaded Sheet-Stringer Panels
Abstract
Compressive tests were made on twenty-one 24S-T aluminum alloy sheet stringer panels 12 inches long and 16 in. wide and of various thicknesses, radii of curvature, and rivet spacing. Curvature increased the strain for buckling of sheet between stringers up to 5.35 times. Fifteen of the panels failed by stringer instability, two failed by separation of rivets, three failed by buckling of stringers and sheet as a unit, and one failed by buckling of sheet between stringers. It is pointed out that the strength of the panels did not differ more than 6% from the theoretical results.
