Tabulated Stress-Intensity Factors for Corner Cracks at Holes Under Stress Gradients


The objective of this paper is to present stress-intensity factors, K, for corner cracks at holes in a tabulated format which can be used to calculate K for general stress fields. Stress-intensity factors were obtained with the weight function method for various stress gradients and crack sizes. The paper also describes a superposition procedure to generate K for general stress distributions by using the data presented. This tabulated information is intended to expand the existing database of reference stress-intensity factors. Results were compared with other published solutions in order to evaluate the analysis procedure. In general, the difference between solutions was within 10%.
