Answer: Failures in aircraft gas turbine engines due to
Chapter 13, Problem 13.18(choose chapter or problem)
Failures in aircraft gas turbine engines due to high cycle fatigue is a pervasive problem. The article Effect of Crystal Orientation on Fatigue Failure of Single Crystal Nickel Base Turbine Blade Superalloys (J. of Engineering for Gas Turbines and Power, 2002: 161176) gave the accompanying data and fit a nonlinear regression model in order to predict strain amplitude from cycles to failure. Fit an appropriate model, investigate the quality of the fit, and predict amplitude when cycles to failure 5000.
