Quigley Scientific: Fracture Mechanics Analysis of Cracked High Speed Rotating Devices


Fracture Mechanics Analysis of Cracked High Speed Rotating Devices


Fracture mechanics analysis of cracked high speed rotating devices was completed as part of an Air Force SBIR (Small Business Innovative Research Program). An innovative parametric analysis method was develop to complete a consistent convergence study. The final mesh models were designed to capture the correct physics occurring in the rotating and crack solution fields. A design sensitivity analysis was completed in a detailed form to produce an analytical variance of the performance and fracture toughness of the system. A state-of-the art understanding was created that produced new knowledge on the true discriminators in rotating body performance.
