AFRL CAI Success Story
Abstract: The two directorates, Boeing, Lockheed Martin, Northrop Grumman, and Bell Helicopter make up the CAI team. The team developed and enhanced finite element software for analysis of composite structures. The StressCheck analysis tool shows a significant improvement in bonded and co-cured joint strength prediction capabilities compared to finite element analysis tools currently on the market.

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck®, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck® as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
