Modern approaches for thermal fatigue damage assessment in automotive components are discussed. Three prominent methods are reviewed, and issues with related material testing, numerical implementations and applications to general thermal cycles are presented. In summary, the chosen methods can produce good thermal fatigue life predictions. Common difficulties include first, prolonged experimental programs to determine the required material parameters, and second, significant computational times involved in analysis of realistic models and loading histories.
