Abstract

The paper presents a method and a device for surface-relief measurements in the study of plastic deformation at the meso- and macroscale levels, with the results to be used in nondestructive testing of materials. A block diagram of the computer-controlled system for measuring surface relief of loaded materials is described whose operation principle relies on a direct method of measurements with a commercial roughness indicator. Major technical data of the automated system are given and causes for measurement uncertainties are analyzed. Typical surface relief distribution patterns obtained with the system are reported.
