DEVICE FOR REPRODUCIBLY APPLYING STRESS TO TEST BODIES

摘要

The invention relates to a device (1) for applying test bodies (2) with a defined stress, comprising a guide (3) having an inner perimeter (3b) with a shape corresponding to the shape of an outer perimeter (2a) of the test body (2), and with a size that permits a translational movement of the test body (2) through the guide (3) with only one degree of freedom into a processing position (4); and engraving means (5) which are designed to exert a predefined cutting application of force on the surface of said test body (2) in response to a test body (2) reaching the processing position (4).
