Conceptualisation et classification des problèmes de fatigue mécanique
[Conceptualization and classification of fatigue problems]
Comptes Rendus. Mécanique, Volume 339 (2011) no. 9, pp. 573-590.

In this article, conceptualization and classification of fatigue problems (in the framework of the Damage Mechanics) are made. Structural loadings induce a local temporal evolution of the “leading” state variable but not vice versa. This argument demonstrates why we should first classify fatigue problems by using structural quantities. The evolution laws, however, are written on the local level: therefore, we provide a classification of fatigue problems based on local quantities. Our ultimate aim is to help to justify a local form of a fatigue evolution law starting from its quasistatic form deduced from Thermodynamics.

On propose de conceptualiser et de classifier les problèmes de calcul de structures dits de fatigue (dans le cadre de la Mécanique de lʼEndommagement). Parce que le concept de fatigue est avant tout un concept que lʼon peut estimer structural plutôt que local, cette classification est faite dʼabord sur des grandeurs structurales. Ensuite, on donne une classification faite sur des grandeurs locales. Lʼobjectif de ces classifications est de favoriser la résolution locale des problèmes de fatigue dʼune classe donnée en aidant à la justification du passage des lois dʼévolution obtenues par la Thermodynamique à celles écrites dans le cadre de la fatigue.
