Experiments for Evlauating 3-D Effects on Cracks in Frozen Stress Models
… rationale. Results show that the normalized stress intensity factor (SIF) for the V-cut case are at least equal to, but in most cases are greater than, the natural crack cases. These results were compared to experimental results from Smith and his associates for motor grains having similar …

Determination of stress intensity factors for cracks emanating from holes in finite thickness plates
The stress freezing photoelastic method is a proven technique for the estimation of stress intensity factors along crack fronts in complex three dimensional problems. Comparisons between previous photoelastic and approximate analytical results have revealed discrepancies in results for the case …

Experimental method of analyzing stress intensity factors and singularity order in rocket motor geometry
A series of frozen stress experiments were conducted on surface flaws of varying aspect ratios in pressurized cylinder with star-shaped cutout in order to study the stress intensity factor distribution along the flaw border and to estimate the loss of the inverse square root singularity when the …
