Fatigue Life Prediction of Flaw-Tolerant Damaged Rotorcraft Structures
Abstract: Paper presented at the American Helicopter Society Annual Forum 74 in Phoenix, Arizona May 14-17, 2018: Fatigue Life Prediction of Flaw-Tolerant Damages Rotorcraft Structures. The presentation and paper report the work done by ESRD and NAVAIR under a SBIR program to develop an analytical approach to predicting the remaining useful fatigue life of metallic components with surface flaws.

“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.”
