Abstract

L'invention concerne un procédé et un dispositif permettant de produire des ondes de choc sous-marines focalisées, par décharge sous-marine multiple simultanée d'étincelles et par focalisation à l'aide d'ellipsoïdes à foyer commun. Selon ce procédé, une pression maximale de l'ordre du GPa est produite dans le foyer commun. L'invention concerne également l'utilisation dudit procédé comme test de vérification de pièces moulées en céramique. Les pièces moulées en céramique soumises au test de vérification sont au départ exemptes de défauts.
