Optimization of measurement accuracy
The comparative characteristic values for tensile strength RIm andRIp0.2 yield strength to tensile test determined by the indentation method lie within a statistically determined confidence range . You will find a current overview of this under the heading Materials.
Tensile test and indentation methods show systematic errors. Material-specific material cards can be created to reduce the deviation. The basis for this is provided by tensile specimens and the associated stress-strain diagrams. Comparison measurements are used to calibrate the results from the indentation method to the results of the tensile test.
