Tests on riveted joints in sheet duralumin
A 1923 technical report from the NASA Technical Reports Server, a record of laboratory tests on riveted lap joints in sheet duralumin, an aluminium alloy, written for engineers and aircraft designers. Its pictures are plain line drawings: a log-scale style graph of rivet strength against rivet diameter with curves for shear, bearing and crushing failure, and dimensioned sketches of plain tensile and typical riveted test specimens. A designer could take the stark engineering diagram style, with its thin black lines, grid, and labelled dimensions.
