Proceedings Papers

Publisher: American Society of Mechanical Engineers
Proc. ASME. GT2023, Volume 11B: Structures and Dynamics — Emerging Methods in Engineering Design, Analysis, and Additive Manufacturing; Fatigue, Fracture, and Life Prediction; Probabilistic Methods; Rotordynamics; Structural Mechanics and Vibration, V11BT23A003, June 26–30, 2023
Paper No: GT2023-102691
... to their ability to improve part stiffness, shift natural frequencies of critical parts from operational ranges, and reduced system noises. Motivation for understanding stiffening structures in aerospace industries (specifically in turbine engines) comes from the potential to improve the designs of low-pressure...
