Stress Intensities Around Surface Flaws in Cylindrical Shells by Stress Freezing.

Abstract

This report documents a set of 24 tests for the determination of K sub I stress intensity factors for isotropic cylinders with longitudinal and transverse part-circular cracks. Part-circular cracks were machined into birefringent Hysol CP5 4290 photoelastic cylinders. The cylinders were then subjected to a stress freezing cycle while under one of two loading conditions: internal pressurization or extension. Slices of the cracks were made at various angles and analyzed with a photoelastic polariscope. A least-squares curve fit of the photoelastic data was used to generate K sub I stress intensity factors. K sub I data are plotted versus slice angle into the crack for various crack parameters.
