Failures in aircraft gas turbine engines due to high Cycles Fatigue Failure cycle fatigue is a pervasive problem. The article "Effect of Crystal Orientation on Fatigue Failure of Single 6 26 0.01819 Crystal Nickel Base Turbine Blade Superalloys" (J. of 13 79 0.01212 Engineering for Gas Turbines and Power, 2002: 161-176) a. R^2 of your choice of model (0.xx) gave the accompanying data and fit a nonlinear regression 7 843 0.00810 model in order to predict strain amplitude from cycles to 8 failure. Fit an appropriate model, investigate the quality of 1016 0.00801 b. Amplitude at 5000 the fit, and predict amplitude when cycles to failure = 1326 0.01495 5000.
