Method and device for determining the properties of a pressure-manipulable test sample

摘要

A method for determining the plasto-elastic properties of a test sample, which can be affected by the action of pressure, includes pressing a test body against a surface of the test sample with a defined force. Plasto-elastic changes of the surface resulting therefrom are recorded during and/or after the pressure application. A centrifugal force generated by rotating the test body around an axis is utilized as a pressure force which is generated by radially movably guiding the test body, which is disposed between the test sample and the axis, relative to the radially fixed test sample.

1. A method for determining plasto-elastic properties of a test sample which can be affected by an action of pressure, the method comprising the following steps:
radially fixing a rigid test sample; pressing a test body against a surface of the test sample with a defined centrifugal pressing force generated by rotation of the test body about an axis; radially moveably guiding the test body, relative to the test sample, between the test sample and the axis, for applying the pressing force; recording resulting plasto-elastic changes in the surface of the test sample at least one of during or after applying the pressing force; recording a temporal course of radial motion of the test body while applying the pressing force to the test sample; and recording a penetration depth of the test body in the test sample.
