Title
(EN) METHOD OF DETERMINING MECHANICAL PROPERTIES OF A SHEET MATERIAL
(FR) PROCEDE DE DETERMINATION DES PROPRIETES MECANIQUES D'UNE MATIERE DE FEUILLE
Abstract
(EN)
Method of determining mechanical properties in the thickness direction of a sheet material (4), by supporting the sheet material (4) on a surface (5); advancing a body (1) having an impacting surface (6, 9) facing the sheet material into engagement with the sheet material (4) supported by said surface (5); sensing and registering the position, velocity or acceleration of the impacting surface (6, 9) of the advancing body (1) as a function of time during the movement of the body (1) in relation to the displacement sensor (3); and analysing said function to obtain the mechanical properties. The present invention also relates to an apparatus for carrying out said method and a use of a body (1) and a sensor (3) in a method or in an apparatus, for determining mechanical properties of a sheet material (4).
(FR)
L'invention concerne un procédé de détermination des propriétés mécaniques d'une matière (4) de feuille, le procédé consistant à placer la matière (4) de feuille sur une surface (5) ; à faire progresser un corps (1), comportant une surface (6, 9) d'impact faisant face à la matière de feuille, en contact avec la matière (4) de feuille placée sur cette surface (5) ; à détecter et à enregistrer la position, la vitesse ou l'accélération de la surface (6, 9) d'impact du corps (1) en progression comme une fonction du temps de déplacement du corps (1) par rapport au détecteur (3) de mouvement ; et à analyser cette fonction pour déterminer les propriétés mécaniques de la matière de feuille. La présente invention concerne également un appareil d'application de ce procédé et l'utilisation d'un corps (1) et d'un détecteur (3) selon le procédé ou dans un appareil, pour déterminer les propriétés mécaniques d'une matière (4) de feuille.
