Abstract
L'invention concerne un procédé et des dispositifs de mesure de la fatigue d'une éprouvette soumise à une sollicitation mécanique. Le procédé, par mesure de l'atténuation acoustique d'ondes ultra-sonores, est caractérisé en ce que l'on contraint l'éprouvette, en ce que l'on provoque la propagation en circuit ouvert d'impulsions ultra-sonores de fréquence prédéterminée le long de l'éprouvette, à un degré quelconque de sollicitation, et en ce que l'on mesure l'atténuation acoustique desdites impulsions. Application à l'observation de la fatigue des métaux notamment en continu.
