Vorrichtung und Verfahren zur Pruefung der Scherbelastbarkeit eines Probekoerpers

The proposal relates to a device for applying a shear stress to an object under test, said device comprising two rigid pressure pads for placing the object under test under pressure, said pads being movable relative to each other along the contact surfaces with the object under test, said device being designed so that the contact surfaces (1a, 2a) of the pressure pads (1, 2) are shaped concentrically in relation to each other and to the object under test (3) and the pressure pads (1, 2) can be swivelled relative to each other about the axis of curvature of the contact surfaces (1a, 2a).
