The Multi-Fastener Analysis Tool (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.

- Simplified user interface provides input of fastener data in pre-defined templates with step by step validation feedback.
Recent News & Events
“As the United States Air Force continues to extend the service life of their aircraft the Aircraft Structural Integrity Program (ASIP) has had to refine the methods it uses to analyze and predict fatigue crack growth. Through the use StressCheck®, coupled with AFGROW, we in A-10 ASIP have been able to more accurately model, predict and analyze critical aircraft structure for the A-10 and other types of structure for non-A-10 system managers. This also allows us within the A-10 to more accurately assess risk for decision makers, streamline aircraft inductions into scheduled maintenance and reduce cost for total life cycle management.”
