Abstract
L'invention concerne un procédé de mesure des déformations longitudinales compensées en température d'une zone d'un élément structurel, ledit procédé prévoyant de reporter sur ladite zone le substrat (1) d'une jauge de contrainte sur lequel sont formés un motif (2) de matériau résistif électriquement et deux paires de bornes (3) en contact électrique avec ledit motif, ledit motif formant un milieu résistif continu selon des directions respectivement longitudinale et transversale et lesdites bornes étant formées de part et d'autre du motif (2) selon la direction respectivement longitudinale pour une paire et transversale pour l'autre paire; de mesurer de façon alternée la tension électrique (Vx, Vy) entre les paires de bornes (3); d'établir une relation entre lesdites tensions en fonction des déformations longitudinales et transversales, ladite relation étant indépendante de la température; d'établir les déformations transversales qui correspondent aux tensions électriques mesurées selon la direction transversale; à partir de la relation et des déformations transversales, de calculer les déformations longitudinales compensées en température en fonction des mesures de tension électrique selon les directions longitudinale et transversale.
