Single Fastener Analysis Tool

The Single Fastener Analysis Tool (SFAT) is a Smart Engineering Simulation App providing accurate computation of the joint stiffness, plate stresses, and fastener loads for single or double shear bolted lap joints connected by a single 3D fastener.

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 of the desired bolted lap joint model using its robust multi-body 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.

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.”

Testimonials

“The p-type element has been used to great advantage in the finite element system ESRD StressCheck, [26]. This software provides the engineer with the means to conduct solution verification in an extremely straightforward manner by simply increasing the degree of the element, monitoring convergence and using Richardson extrapolation reliably to estimate the error. This can be conducted automatically by the software thereby enabling the engineer to concentrate on the engineering rather than the simulation. StressCheck has also been used to develop ESRD’s Handbook and Toolbox applications. The first of these provides engineers with a repository of parameterised standard problems of the type found in texts like Roark’s “Formulas for Stress and Strain”, [27]. The second, Toolbox, is a tool that can be used to parameterise a company’s range of components for rapid and reliable analysis by non-expert analysis. Toolbox then is an exemplary of the way in which the democratisation of simulation can be applied.”
