While frequency-domain methods offer powerful approximations, many fatigue problems still require working directly with the vibration signal itself. Time-domain approaches remain the reference for capturing complex loading effects and accurately reproducing real-world damage mechanisms.
In Time Domain Methods for Fatigue and Damage Estimation, I review the main techniques used to evaluate fatigue damage from raw time histories, from cycle counting methods to cumulative damage models. The paper highlights their advantages, limitations, and practical applications in durability engineering.
This review complements my research on vibration fatigue and durability prediction by providing the foundations needed to analyze, model, and validate damage directly from measured operational data.
