The Stability of Orthotropic Elliptic Cylinders in Pure Bending
This is a 1937 NASA technical report on the buckling stability of orthotropic elliptic cylinders under pure bending, issued as a research record for aeronautical engineers. The two photographs show test cylinders after failure, with wrinkled, collapsed metal skin and visible rivet lines, offering a designer reference for crumpled sheet-metal texture and structural failure forms.
