文摘
- •
Microstructure, hardness and residual stress effects on fatigue are studied.
- •
The bending fatigue endurance limit of induction hardened gears is predicted.
- •
Model predictions are compared to experimental single tooth bending fatigue tests.
- •
The proposed model provides reasonable predictions of the bending endurance limit.
- •
The crack initiation location is more challenging to predict with such model.
