Title (EN) TENSILE TESTING MACHINE
(FR) MACHINE D'ESSAI A LA TRACTION
Abstract: front page image
(EN)Tensile testing device, which measures the strain for a tensile testing specimen (24) by means of the relative displacement of the fastening means (2, 14), as a result of that the attachment of the tensile testing specimen (24) is performed in such a manner which is independent of the applied tensile testing force. Furthermore, the device provides a contact-free dimension measurement (26, 27) of the tensile testing specimen (24) simultaneous to the tensile testing procedure. The device enables at the same time a compensation of measured values for machine strain and friction forces, and the pulling speed in the tensile testing procedure is controllable, depending in the appearance of the tensile test curve. Moreover, the maximum tensile stress, various standardised strain measures and the fracture area may be calculated.
(FR)Ce dispositif d'essai à la traction sert à mesurer la contrainte d'un spécimen (24) soumis à cet essai, grâce au déplacement relatif de moyens de fixation (2, 14), cette fixation du spécimen (24) s'effectuant en conséquence indépendamment de l'application de la force d'essai à la traction. En outre, ce dispositif permet d'obtenir une mesure de dimensions (26, 27) du spécimen (24), sans contact avec celui-ci, simultanément au processus d'essai à la traction, et il permet en même temps une compensation des valeurs mesurées pour les forces de friction et de contrainte de la machine, la vitesse de traction lors du processus d'essai à la traction pouvant être régulée, en fonction de la forme de la courbe de l'essai. De surcroît, on peut calculer la contrainte maximale d'essai à la traction, diverses mesures de contrainte standardisées, ainsi que la zone de rupture.
