STATIC-PRESSURE TESTS OF THIN-WALLED BOX STRUCTURES,
Abstract
Six medium-steel boxes were collapsed under external air pressure to obtain criteria for the design of deckhouses of ships subjected to nuclear air blast. All boxes failed by plastic buckling of the edges. For two unreinforced cubes doubling the ratio of plate thickness to plate width quadrupled the collapse pressure. Reducing the aspect ratio (plate length to plate width) from 2.0 to 1.0 resulted in an increase of strength of 84 percent for two boxes with no edge reinforcement. A box reinforced along the edges failed at a pressure 3.4 times as great as the pressure at which an unreinforced box of equal weight failed. (Author)
