Stress Intensities for Low Aspect Ratio Surface Flaws in Pressurized Thick Walled Tubes.
Abstract
A series of stress freezing photoelastic experiments were conducted on thick walled cylinders containing longitudinal low aspect ratio surface flaws under internal pressure. Slices normal to the cylinder axis near the flaw midpoint were analyzed photoelastically and the SIF was estimated from a technique involving a computer-assisted least squares analysis of the photoelastic data. Results were compared with the Bowie-Freese solution to the plane problem, which is viewed as an upper bound to the problem, the Underwood Approximation, and an approximate theory due to F. W. Smith.
