Method and device for the determination of by pressure influenceable properties of a test specimen

摘要

In the case of a method for determining the influenced by the action of pressure plasto - elastic properties of a test specimen (3), a test object (5, 6) with a defined force against a surface of the test piece is pressed, and the resulting plasto - elastic changes in the surface, during and / or after the application of pressure is detected. The rotation of the test specimen about an axis (1) the centrifugal force generated in the form of a pressure force is used, with the test specimens to their application and guided to move radially in relation to the radially fixed unit under test between the latter and the shaft is disposed.
