Summary

This review examines fatigue limit assessment methodologies based on thermography, covering temperature-based, energy dissipation, and thermodynamic entropy indicators. The paper outlines the current state of research in this field and identifies areas for future study involving fatigue behavior analysis using thermal imaging techniques.

Fatigue limit assessment methodologies based on the thermography technique are comprehensively studied in this work. Three fundamental indicators pertaining to temperature increase, intrinsic energy dissipation, and thermodynamic entropy are discussed in sequence. The main train of thought of thermo-based research is outlined. The main objective of this paper is, on the one hand, to describe some works that have been accomplished in this field and, on the other hand, to present further potential for future studies involving fatigue behaviors and thermography approaches.
