Model for Fatigue Life Prediction of Titanium Alloys. Part 2. Model Testing and Analysis of Obtained Results

  • 135 Accesses

We present the results of fatigue life prediction for smooth specimens of VT3-1 titanium alloy in seven structural states using the proposed model. The prediction results presented in the form of fatigue curves (S–N curves) before crack initiation and fracture are compared with the experimental data and their good agreement is shown. For comparison, the life prediction results are presented using the fatigue fracture diagrams constructed experimentally during the crack growth process.
