StressCheck Tutorial: Modeling and SIF Extraction for a 3D Loaded Crack Face
Abstract: Defining and assigning a formulaic, normal residual stress distribution to a part-thru crack surface, then using the Contour Integral Method – Loaded Crack (CIM-LC) to extract stress intensity factors (SIF) for a 3D plate + hole with loaded corner crack.

“In the case of the through crack configuration, the comparison of experimental and StressCheck® derived geometry factors showed a close correlation and were an improvement to solutions provided in AFGROW at the time. Based on the results of this research, StressCheck® pin-loaded lug geometry factors have since been incorporated into the AFGROW software.”
