The stress criterion of a tension member with graded flexural stiffness : contribution to the problem of "clamping effect" outside of the elastic range
A 1936 NASA technical report, published in English from a NASA Technical Reports Server scan, on the stress criterion for a tension member with graded flexural stiffness and the clamping effect beyond the elastic range. The pictures are engineering graphs with curved plotted lines, log-scale axes, and labelled series such as s values, stress figure and cmkg units. A designer could take from them the look of dense technical plotting: thin curves fanning across grids with small circle markers at data points.
