Optimization of the measuring accuracy
The comparative characteristic values for tensile strength RIm and RIp0.2 yield strength determined by the indentation method lie within a statistically determined confidence interval. You will find a current overview under the heading Materials.
Tensile test and indentation method show systematic errors. Material-specific material cards can be created to reduce the deviation. The basis for this is provided by tensile tests and the corresponding stress-strain diagrams. The results from the indentation method are calibrated to the results of the tensile test by means of comparative measurements.
