Effect and measurement of the machine compliance in the macro range of instrumented indentation test
- The contribution concerns the strong effect of the machine compliance in the upper macro range of the instrumented indentation test on hard materials. To achieve a minimum uncertainty in determination of the machine compliance the measurement and analysis needed for the determination are studied in detail. Based on the assumption that the hardness and/or the indentation modulus are force independent, four methods on the determination of the machine compliance are described. Experimental results of a commercial testing machine up to 2500 N and of a standard machine up to 200 N are analyzed. The results show that the uncertainty of the compliance is usually higher than requested for a precisely enough determination of hardness and further materials parameters. Especially for the calibration of reference materials with high hardness and/or Youngs modulus, the machine compliance should be limited in ISO 14577 part 3, 2003 [1].
