Les disques de turbo-réacteur fonctionnent à haute température et chargements élevés. Ils sont soumis à des déformations thermiques et mécaniques. Les contraintes résiduelles de compression sont introduites en surface par grenaillage. Durant le service, les contraintes appliquées sont réduite jusqu'à zéro ou passent en tension, cela est causé par la fatigue oligocyclique. La base de données FMA des contraintes résiduelles dans les disques en fonction du nombre de cycles, mise en place par FMA-PROTO, a montré une tendance linéaire. La pente de la droite dépend de la sévérité des conditions de fatigue et de service cumulés. Les courbes de Wöhler obtenues en flexion rotative ont montré une augmentation de la durée de vie pour les échantillons ...
