A computer program based on the theory of thin shells of revolution was used to map axial bending moment and stress, cross-wall shear stress, and circumferential stress along the length of a 6-in. diam cylinder subjected to a radial line load. There were no significant differences between the experimental and the analytical results. The experimental tests were performed with a hydraulic test fixture designed to impose a radial line load 3/8-in. (9.5 mm) in width. Three test specimens were instrumented. A group of uninstrumented specimens was also loaded to failure to determine the exact position of failure. The cross-wall shear stress and flexural stress at the failure loads as determined by the computer program showed that the flexural stress was maximum and the cross-wall shear stress was comparatively low at the point of failure.
