Résumé
On décrit une barre de pression pour grandes charges caractérisée par deux impulsions symétriques engendrées aux deux extrémités de la barre, et la méthode à utiliser pour l'interprétation des signaux. On donne les premiers résultats obtenus avec des éprouvettes de grandes dimensions en utilisant des techniques optiques de mesure.
Abstract
A high load pressure bar characterized by symmetric pulses coming from the two ends is described together with a method for interpretation of signals. First results obtained by testing large specimens using optical techniques are reported.
