Abstract

Appareil pour déterminer le comportement qu'aura une matière visco-élastique pendant son élaboration. L'appareil comprend un premier vérin pour soumettre un échantillon d'essai ou une éprouvette à une contrainte compressive initiale, un second vérin pour appliquer à l'éprouvette une contrainte d'essai supplémentaire et un système pour contrôler la relaxation des contraintes dans la matière d'essai, caractérisé en ce que les deux vérins 70, 28 sont montés de manière que leurs pistons se déplacent suivant des directions mutuellement parallèles. Industries du caoutchouc et des matières plastiques.
