Bending Tests of Circular Cylinders of Corrugated Aluminum-alloy Sheet
A 1937 NACA technical note on bending tests of circular cylinders made from corrugated aluminum-alloy sheet, written for aircraft structures engineers and published by the National Advisory Committee for Aeronautics. The pictures are black-and-white photographs of failed corrugated cylinders and the test rig, showing buckled ribs, split seams, and a machined backplate. A designer might take from them the look of rippled metal sheet under compression, with its fold lines and crushed corrugations.
