) of the stress signal, which reflects the overall energy of the vibration. Spectral Moments E[P]=m4m2cap E open bracket cap P close bracket

A more recent approach that uses a weight index to combine upper and lower bounds of fatigue damage, often providing high accuracy across various spectral shapes. Why It Matters vibration fatigue by spectral methods pdf

Several spectral methods have been developed for vibration fatigue analysis:

Spectral methods convert the power spectral density (PSD) of stress at a critical point into an expected fatigue damage rate. The key steps are:
