Abstract

Méthode de contrôle non destructif d’un ensemble de plusieurs structures (401,402), les structures (401,402) dudit ensemble étant sensiblement identiques, chaque structure (401,402) étant équipée d’une pluralité de capteurs d’ondes élastiques identiques et positionnés à des emplacements sensiblement identiques sur chacune des structures, la méthode comprenant les étapes de : Pour chaque couple de capteurs, déterminer un signal caractéristique de la propagation d’une onde élastique ultrasonore dans la structure le long d’un chemin reliant les capteurs du couple, Regrouper les signaux obtenus par groupes correspondant à des chemins entre capteurs sensiblement identiques Extraire de chaque signal, une pluralité de caractéristiques représentatives du signal, Au sein de chaque groupe de signaux, déterminer un indicateur de dommage représentatif d’une distance entre chaque vecteur de caractéristiques associé à un couple de capteurs et une moyenne desdits vecteurs de caractéristiques sur l’ensemble des signaux du groupe, Comparer l’indicateur de dommage à un seuil prédéterminé.
