Title (EN) RHEOMETER
(FR) RHEOMETRE
Abstract:
(EN) Apparatus and a method for investigating dynamic rheological properties of a viscoelastic medium involves oscillating at least one shear wave generation surface in a container containing the viscoelastic medium such that shear waves generated thereby impinge on two spaced shear wave receiving surfaces, the receiving surfaces being spaced by different distances from the source of shear waves impinging thereon. Transducers are provided for the shear wave receiving surfaces capable of generating output signals dependent on the variations in physical parameters of heating the wave receiving surfaces induced by the oscillating shear wave generation surfaces.
(FR) Appareil et procédé permettant d'étudier les propriétés rhéologiques dynamiques d'un milieu viscoélastique, dans lesquels on fait osciller au moins une surface de genération d'ondes de cisaillement de manière que les ondes ainsi générées frappent deux surfaces de réception d'ondes de cisaillement mutuellement espacées, lesdites surfaces de réception se trouvant à des distances différentes par rapport à la source des ondes de cisaillement qui les frappent. On relie des transducteurs aux surfaces de réception des ondes des cisaillement, capables de générer des signaux de sortie qui sont fonction des variations des paramètres physiques affectant les surfaces réceptrices des ondes, induites par les oscillations des surfaces de génération des ondes de cisaillement.
