- •
A new finite element-based mesoscale fatigue model is developed.
- •
Inelastic hysteresis energy is used to predict short fatigue crack formation.
- •
Microscale modeling approach is able to reproduce known fatigue experimental facts.
- •
It is able to predict the fatigue behavior from low up to very high cycle region.
- •
Initial cracks need to be larger than a critical value to affect fatigue life.
