"Results are presented of tests of two sets of 20 curved-sheet specimens to determine the effect of normal pressure on the critical compressive and shear stress of curved sheet. It was found that normal pressure raised the critical compressive and shear stress of curved sheet except when outward bulging occurred in compression, in which case the critical stress was lowered by normal pressure." . . . . . "Effect of normal pressure on the critical compressive and shear stress of curved sheet" . . . . "Results are presented of tests of two specimens tested to study the effect of normal pressure on the critical compressive stress for thin curved sheets. These specimens are designated by their respective rib spacings of 10 inches and 30 inches. The relationship between compressive stress and normal pressure at which buckles disappeared is independent of whether the buckles were made to disappear by increase of normal pressure or decrease of compressive stress." . . . .
