文摘
- •
A frequency-domain criterion based on the critical plane is reformulated.
- •
The critical plane is dependent on the PSD matrix of the stress tensor.
- •
The PSD of an equivalent stress is used to estimate fatigue damage.
- •
Different damage models are implemented in the frequency-domain criterion.
- •
Comparisons with experimental and time-domain criterion results are satisfactory.
