In this paper, one industrial example is detailed, to show the effectiveness of the methodology: a damage analysis of a truck cast iron cylinder head. © 2021 Hubert Blondet Arobas Technology and Kamilia Barthoux Volvo GTT France.

Main text The aim of this report is to present the hypotheses and main results of a new FEA methodology which automatizes the Life Time Assessment (LTA) or durability analysis of a truck cast iron cylinder head, regarding a specific duty cycle or customer usage and thermomechanical failure modes. In details, the methodology consists to convert a duty cycle FATIGUE DESIGN 2021, 9th Edition of the International Conference on Fatigue Design Fatigue software improvement for calculating by FEA a complete map of the damage due to a duty cycle, regarding thermo mechanical failure mode. Application to a truck cylinder head lifetime assessment Hubert Blondet 1 , Kamilia Barthoux 2 Abstract Physical tests considering real customer usages for truck engine components durability validation, are very expensive and time consuming. Using a calculation method enabling to determine cumulative damage due to a specific duty cycle, seems then a priority, especially for fatigue thermo-mechanical failure mode. However, most of these complex engine components have several brittle areas, and the current calculation methods within Volvo GTT France allow only to analyze one or few critical areas, without considering the complete behavior of the component in the analysis. mech Hubert B y *E-mail addresses: hubert.blondet@arobas-technologies.com / kamilia.barthoux.2@volvo.com
