Abstract

Procédé de recherche de fissures sur des pièces d'épreuves telles que des éprouvettes ou des pièces, notamment au cours d'essais sur des machines d'essais dynamiques de matériau. On excite la pièce d'épreuve 13 à sa fréquence propre pendant l'essai et l'on détecte une modification de la fréquence propre correspondant à l'apparition d'une fissure L'invention permet une recherche facile et peu onéreuses y compris dans des conditions d'essais à hautes températures.
