Abstract

Dispositif comportant une pièce de blindage (10) et un capteur de déformation (2) fixé sur la pièce de blindage, le capteur de déformation étant configuré pour se déformer sous l’effet d’une contrainte Ca appliquée sur la pièce de blindage, de manière élastique lorsque la contrainte appliquée Ca est inférieure ou égale à une contrainte de seuil Cs, et de manière plastique lorsque la contrainte appliquée Ca est supérieure à la contrainte de seuil Cs, la contrainte de seuil étant telle que Cs < Ce min et (Ce min – Cs)/Cs < 20%, Ce min étant la contrainte d’endommagement minimale de la pièce de blindage. Figure pour l’abrégé : Fig 1.
