A SIMPLE PROCEDURE FOR ESTIMATING STRESS INTENSITY FACTOR IN REGION OF HIGH STRESS GRADIENT

Simple procedures for estimating stress intensity factors of through-cracks and semi-elliptical cracks in regions of high stress gradient have been presented. Stress intensity factors for cracks emanating from an unfilled hole, an interference fitted hole, a hole with a concentrated load, and on the external and internal surfaces of a pressurized cylinder, were determined by these procedures. These procedures should be of practical interest for engineers involved in day-to-day problems in fracture mechanics. (Author)
