Abstract
(EN) The invention relates to an ultrasonic-rheological method for determining the dynamic threshold force in materials with plastic-type behaviour, comprising: coupling an ultrasonic transducer to the lower plate of a torsional rheometer with parallel plate geometry, b) adjusting the distance between plates of the rheometer to a gap of between 0.1 and 1 mm, c) introducing the sample of material with plastic-type behaviour between the rheometer plates fitted in the previous step, d) initiating the emission, by the transducer, of longitudinal ultrasonic waves at a frequency interval of between 0.1 and 20 MHz, and e) synchronising said acoustic emission with the rheological test consisting of subjecting the sample to the action of a mechanical stress.
(ES) Procedimiento ultrasónico-reológico para la determinación del esfuerzo umbral dinámico en materiales con comportamiento plástico, que comprende: a) acoplamiento de un transductor ultrasónico a la placa inferior de un reómetro torsional con geometría de placas paralelas, b) ajuste de la distancia entre placas del reómetro a un intervalo comprendido entre 0,1 y 1 mm, c) introducción de la muestra de material con comportamiento plástico entre las placas del reómetro ajustadas en la etapa anterior,d) comienzo de la emisión por el transductor de ondas ultrasónicas longitudinales en un intervalo de frecuencias comprendido entre 0,1 y 20 MHz, e) sincronización de dicha emisión acústica con el ensayo reológico consistente en el sometimiento de la muestra a la acción de una solicitación mecánica.
(FR) Procédé ultrasonore-rhéologique pour la détermination de la contrainte seuil dynamique dans des matériaux à comportement plastique. Ledit procédé consiste à a) accoupler un transducteur ultrasonore à la plaque inférieure d'un rhéomètre à torsion possédant une géométrie de plaques parallèles, b) ajuster la distance entre les plaques du rhéomètre à un intervalle compris entre 0,1 et 1 mm, c) introduire l'échantillon de matière à comportement plastique entre les plaques du rhéomètre ajustées à l'étape antérieure, d) commencer l'émission par le transducteur d'ondes ultrasonores longitudinales dans un intervalle de fréquences compris entre 0,1 et 20 MHz, e) synchroniser ladite émission acoustique avec l'essai rhéologique en soumettant l'échantillon à l'action d'une sollicitation mécanique.
