SFAT provides accurate computation of the joint stiffness, plate stresses, and fastener loads for single or double shear lap joints connected by a single fastener.
Single Fastener Analysis Tool (SFAT)
3D multi-body contact bolted joint analysis via a targeted Smart Engineering App.
Through a simple and intuitive interface, the user can provide engineering input data from which SFAT automatically builds, solves, and post-processes a fully 3D StressCheck® finite element mesh using its robust contact algorithm.
Key Features and Advantages
- Simulate 3D-contact with high quality results without having to build a FE mesh.
- Solution time is reduced from hours to minutes.
- Simplified user interface provides input of the appropriate fastener data in pre-defined templates with step by step validated feedback.
- Easy to Learn and Easy to Use. Built-in Results Viewer provides dynamic viewing of the FE mesh and stress fringe contours.
- Supports single and double shear joints with washers, bushings, shims, protruding head or countersink fasteners, metallic or laminate composite plates.
- Solutions obtained with StressCheck, verified by p-extension.
- Modeling approach validated with experimental results
- Supports US and SI units.
Recent News & Events
“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.”
