- •
Critical plane criteria were used to estimate biaxial fatigue crack initiation angle.
- •
Stress intensity factor and J integral values were calculated using FEA through the loading cycle.
- •
Fatigue crack propagation angles were estimated for both specimens.
- •
The loading phase shift angle does influence the crack propagation angle, as our results show.
- •
Both specimens are useful for fatigue crack propagation studies.
