Helpful Hints and Tips: 3D Stiffened Lug Stress + Crack SIF Analyses
This end-to-end (E2E) example focus on importing a 3D stiffened lug, performing a detailed stress analysis, and extracting the location of the maximum 1st principal stress in the lug. Then, the example continues into a fracture mechanics analysis where an elliptical crack is embedded at the location of the maximum 1st principal stress, the model is re-solved, and stress intensity factors (SIF’s) are extracted.

“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.”
