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). |
