MFAT provides effortless modeling of single or double shear joints, including lap joints, splice joints, and doublers (with or without a repair cutout). MFAT supports metallic and composite plates, and allows for any number of fasteners with neat fit, interference fit or clearance fit.
Multi-Fastener Analysis Tool
Single and double shear joints with unlimited fastened connections.
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

- 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.
Recent News & Events
“A screening of existent commercial and non-commercial tools was carried out in respect to their fracture mechanics capabilities, their design abilities, implementation as well as their complexity. Although, there are many software possibilities, only those within the reach of the author were evaluated. This resulted in the selection of the commercial tool StressCheck. The assessment of crack propagation on compact tension and two stringer specimens governed by the Paris and Forman regimes was satisfactory compared with experimental results using the material data from simple standard specimens.”
