Abstract

On fixe des moyens de mesure de déplacement (15, 16) sur l'élément de construction. On perce un trou (20, 21) dans la zone de mesure et on applique une pression d'alimentation à un vérin plat introduit dans le trou. On analyse les déplacements mesurés en fonction de la pression d'alimentation pour déterminer la contrainte à partir d'une pression d'alimentation qui compense sensiblement la déformation de l'élément due au perçage du trou. Les moyens de mesure comprennent deux bras (15) qu'on fixe sur l'élément en deux points d'ancrage respectifs (X) alignés parallèlement à une direction de mesure, et au moins deux capteurs de déplacement (16) montés sur les bras de part et d'autre des points d'ancrage pour mesurer les variations d'écartement entre les points d'ancrage. Les bras (15) laissent entre eux un intervalle à travers lequel on perce le trou, en position médiane par rapport aux points d'ancrage.
