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.

“We have found StressCheck® very useful for computational fracture mechanics for both metallic and composite components. In recent years it has been extensively used in determining beta factors for RAAF’s C-130 Wing DTA locations and associated generic research.”
