Test methods and testing device for non-destructive determination strength - and / or by employing relevant material properties of a sheet-metal component to be tested on the basis of the planar torsion test

摘要

The invention relates to a test method for determination of shaping technology of relevant material properties of a test sheet (1) on the basis of the planar torsion test, in which at least one section of the metal plate (1) by means of clamping tool is subjected to torsional loading and at least the torque and angle of rotation of the clamping tool (2, 3) are detected. In this case, a stationary and fixed from the sheet metal plate component (1) between the top and bottom side of the respective test area (12) of the sheet-metal (1) arranged pins (2, 3) is clamped, then the clamping pins (2, 3) perpendicularly to the plane of the sheet in the test region (12) in the same direction relative to the stationary plate component (1) are rotated, and the to the rotation of the clamping pins (2, 3) and thus to the local of the shearing of the uniform (1) in the test region (12) of torque needed and the relative angle of rotation of the clamping pins (2, 3) and / or protection against torsion, time are measured and recorded.
