StressCheck Tutorial: Sample Global-Local Workflow for a 3D Rib Stress Analysis
Abstract: Sample global-local workflow using imported NASTRAN gridpoint forces (in CSV format) to represent cap axial and web shear loading at a rib section. Application of imported Total Load At A Point forces using TLAP-Traction, Near Faces over the cut sections and fastener locations along the rib. Detailed breakout stress analysis with peak stress extractions at holes a sufficient distance from the regions of TLAP-Traction assignment.

“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.”
