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.

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck®, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck® as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
