StressCheck Tutorial: 3D Modeling of a Skin-Stiffener-Fasteners Assembly (Partial Contact)

Abstract: Modeling of a 3D integrated skin/fasteners (i.e. “plugs”) and stiffener assembly for a partial multi-body contact analysis in which only the stiffener stresses are of interest. 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.

Testimonials

“At DST Group, we have effectively used StressCheck^® over the last 10 years to determine accurate stress intensity factors. The results have been used to improve our residual strength and structural life estimates for aircraft in service with the Royal Australian Airforce, including C-130, P-3C and F/A-18 A/B. We have found it to be extremely easy to use and a very versatile code with which to create parametric models.
We have recently used StressCheck^® to obtain improved stress intensity factor solutions (Improved stress intensity factors for selected configurations in cracked plates and Improved stress intensity factors for a single corner crack at a loaded fastener hole) for five key generic configurations. These transferable parametric results have been published externally. One specific example is the non-linear contact analysis of a cracked, filled fastener hole, with both fastener and remote plate loading.”
