The use of spectral methods in vibration fatigue analysis offers a better understanding of the fatigue behavior of structures under complex and random loading conditions. By transforming the time-domain signal into the frequency domain, spectral methods provide a more efficient and accurate approach to analyzing vibration fatigue.
: He could tweak a beam's thickness and instantly see how it affected the fatigue life, allowing him to optimize structures in real-time. The Quest for the Perfect PDF vibration fatigue by spectral methods pdf better

❌ If your PSD is perfect but the peaks look clipped or have spikes (kurtosis ≠ 3), spectral methods will underestimate damage.
