Strength Tests of Thin-Walled Duralumin Cylinders in Compression
A 1934 NACA technical report on compression strength tests of thin-walled duralumin cylinders, published by the National Advisory Committee for Aeronautics for aeronautical engineers and researchers. The plates show buckled and collapsed tubes, test rigs and loading apparatus, with clear views of how thin metal shells deform under load; a designer could draw on the crumpled diamond-patterned wall forms as sources for structural or industrial surface textures.
