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.

“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.”
