Method and device for detecting, picking up and measuring the elastic and elastoplastic deformation of a surface of a test-piece arising under the effect of a load

摘要

A method and a device are described for detecting, picking up and measuring hard materials with low ductility, especially the hardness penetration of the edge layer of a test-piece (1), the surface of the test-piece (1) being loaded using a loading body (2). In addition to the plastic penetration distance (3), the extent of the elastic deformation (6) of the surface of the test-piece (1) is measured, starting from the loading point and as a function of the radial distance from the loading body (2). <IMAGE>
