High Cycle Fatigue Life Prediction of Single‐Crystal Specimen Based on TCD Method and Crystal Plasticity Theory

International Journal of Aerospace Engineering, Volume 2023, Issue 1, 2023., 2023
This paper performs a comprehensive investigation on the high cycle fatigue (HCF) life prediction of turbine blade with film cooling holes. The modified theory of critical distance (MTCD) method is proposed to estimate the fatigue life of the specimen considering the notch sensitivity coefficient and multiaxial stress effect.

Dynamic Characteristics Analysis of 3D Blade Tip Clearance for Turbine Blades with Typical Cracks

International Journal of Aerospace Engineering, Volume 2022, Issue 1, 2022., 2022
As well known, the crack is a typical fault of turbine blades, which is difficult to detect due to the weak fault features contained in the rotor vibration. Although some fault diagnosis methods based on blade tip timing (BTT) are proposed to detect blade cracks, the limited fault features can be extracted because the BTT signals contain only one ...
