CAI Composite Joint Analysis
Abstract: The Composites Affordability Initiative (CAI) was established to reduce the cost of composite structures essential to high-performance aircraft. A team was established that consisted of the Air Force Research Laboratory Materials and Manufacturing Directorate, the Air Vehicles Directorate, the Office of Naval Research, Boeing, Lockheed Martin, Northrop Grumman and General Electric Aircraft Engines. Early in the program the team recognized that in order for lower cost concepts to be accepted by the engineering community, accurate analysis of predicted performance was required.

“Small errors in modeling can lead to substantial errors in joint performance prediction. To alleviate this problem, the CAI used the handbook functionality of ESRD Inc.’s (St. Louis, Mo.) trademarked StressCheck® P-version finite element software to develop reusable models of typical joints.”
