Verfahren und Vorrichtung zum Bestimmen des deformationsmechanischen Verhaltens von festen und zaehfluessigen Stoffen,insbesondere von Stoffen in viskoelastischem Zustand

摘要

A process for determining the elastic and irreversible plastic parameters of materials of consistencies ranging from doughy to molten at a constant rate of extension, and an apparatus for carrying out said process in which two pairs of wheels separated by a predetermined distance act on a bar-shaped test specimen at a constant peripheral speed and in which molten specimens are supported by the surface of a liquid.
