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.

“Accurate and reliable stresses and Stress Intensity Factors are required for determination of static and residual strength and for crack growth analyses in analysis tools such as AFGROW. For some geometries, industry solutions are either insufficient or nonexistent. The geometry, applied forces, and crack shapes and dimensions must be modeled reasonably well to obtain useful engineering data. The p-version finite element software StressCheck® (ESRD, Inc., St. Louis, Missouri, USA) is used to demonstrate how accurate finite element solutions can lead to good quality engineering analysis.”
