StressCheck Tutorial: 3D Modeling of a Skin-Stiffener-Fasteners Assembly (Full Contact)
Abstract: Modeling of a 3D skin, stiffener and fasteners (as bolts with heads/nuts) assembly for a full multi-body contact analysis. In-plane axial loads only, in which the stiffener/skin load ratio is 0.55. Defining parts for each subassembly for easier creation and assignment of contact zones. Model pre-processing only.

“Small errors in modeling can lead to substantial errors in joint performance prediction. To alleviate this problem, the CAI used the handbook functionality of ESRD Inc.’s (St. Louis, Mo.) trademarked StressCheck® P-version finite element software to develop reusable models of typical joints.”
