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. 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.

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
