Discuss on Uncertainty Evaluation for Mechanical Properties Testing of Metallic Materials

The idea of uncertainty evaluation for mechanical properties testing of metallic materials was discussed, and it was proposed that the measured values should be classified as direct measured values and indirect measured values. Through the analysis of measured value transfer process, the sources of uncertainty of direct measured values were divided into three parts to carry on the analysis. After the completion of the uncertainty evaluation of the direct measured values and the other sources, the uncertainty evaluation of the indirect measured values could be combined by these components.
