Le coefficient de concentration de contraintes est un outil peu précis. Il est illusoire d'espérer une incertitude inférieure à 10 %. Lorsqu'il est nécessaire de connaître avec précision la contrainte dans une zone de concentration, il faut la mesurer ou la calculer directement par une méthode numérique. 2, record 3, French, - facteur%20de%20r%C3%A9duction%20de%20la%20r%C3%A9sistance%20%C3%A0%20la%20fatigue

L'entaille [...] n'est pas la seule particularité morphologique susceptible de créer une concentration de contraintes. Les épaulements, les trous et, en règle générale, toutes les discontinuités de forme provoquent le même phénomène. Cependant, on utilise souvent le terme d'entaille pour schématiser tous les cas possibles. L'effet d'une entaille sur une pièce est la création de concentrations de contraintes locales. 2, record 3, French, - facteur%20de%20r%C3%A9duction%20de%20la%20r%C3%A9sistance%20%C3%A0%20la%20fatigue
