Abstract

La présente invention concerne un procédé permettant de déterminer l'état de fatigue d'une éprouvette contenant du métal, le procédé utilisé n'exerçant pas d'influence négative sur les propriétés de fatigue de l'éprouvette testée, malgré la présence d'un électrolyte, et le procédé revendiqué et le dispositif de capteur de fatigue électrochimique (Electrochemical Fatigue Sensor / EFS) servant à mettre en oeuvre le procédé revendiqué permettant de mesurer les dommages par fatigue à différents moments durant la durée de vie utile de la structure métallique. L'éprouvette testée est placée dans une cellule EFS contenant une électrode et un électrolyte, qui n'a aucun effet de dégradation sur l'éprouvette testée et est en contact avec l'éprouvette testée. L'électrolyte utilisée avec le dispositif EFS et le procédé de l'invention peut être incorporé à un matériau gélifiant. Une tension est appliquée, ou est créée galvaniquement, entre l'éprouvette et l'électrode, et le courant est mesuré en passant par l'électrolyte durant une période pendant laquelle l'éprouvette est soumise à des contraintes cycliques. L'analyse des composantes de déformation élastique et plastique courantes transitoires permet de déterminer et/ou d'estimer l'état de fatigue et la durée de vie utile restante de l'éprouvette.
