Multi-Fastener Analysis Tool

Multi-Fastener Analysis Tool

The Multi-Fastener Analysis Tool (MFAT) is a Smart Engineering Simulation App providing effortless modeling of single or double shear joints, including lap joints, splice joints and doublers (with or without a repair cutout), within a Planar setting. MFAT supports metallic and composite plates, and allows for any number of fasteners with neat fit, interference fit or clearance fit.

MFAT accounts for both the radial stiffness of the fastener and the fastener fit, including the nonlinear interaction between the fastener shank and the fastener hole. MFAT also includes the effect of the shear/bending stiffness of each fastener, the value of which can be accurately computed with SFAT. The FE mesh is built ‘on the fly’ based on input provided by the user in a very intuitive interface. Fastener load transfer results obtained with MFAT are presented in tabular form and depicted graphically, and they compare well with experimental data published in the literature.

Key Features and Advantages

  • Solutions are obtained with StressCheck, with quality verified by p-extension.
  • Modeling approach validated with experimental results.
  • Built-in results viewer provides dynamic viewing of FE mesh and stress fringe contours.
  • Supports US and SI units.
  • Simulate influence of fastener fit in load transfer.
  • Solution time is reduced from hours to minutes when compared with standard FEA.
  • Simplified user interface provides input of fastener data in pre-defined templates with step by step validation feedback.

Testimonials

The software provides a highly reliable and user-friendly production stress analysis tool that will replace the Finite Element Method (FEM) tools and failure criteria the experts currently employ for analyzing bonded joints. The software includes an FEM-based handbook format, which allows non-experts to utilize models prepared by specialists. The handbook problems include built-in failure criteria, geometric and material nonlinearities, and the modern FEM technology provides better error control and the treatment of very large aspect ratios.”
