Strength of Rectangular Flat Plates Under Edge Compression
A 1931 NASA technical report on how rectangular flat metal plates buckle and fail when compressed along their edges, issued by the NACA-era research program for aeronautical engineers and structural testers. The pictures are black-and-white photographs of tall narrow test plates showing buckling patterns, alongside the testing machine with grips and loading frame. A designer could take from them the look of bulging, wave-like deformation in thin metal and the heavy industrial testing apparatus behind it.
