Study on the Electrometric Method to Measure the Young’s Modulus of Metal Materials

Article Preview

Abstract:

Young's modulus is one of the basic mechanical properties of materials, so its accurate measurement has great engineering significance. Electrometric method is one of the commonly used method. Proceeding from experimental techniques, this paper studies the key factors which affect the result of the experimental measurement, including the influence of the uneven load, the pre-stretching, the hardening time of the strain gauge binder, and sticking quality of strain gauge; comprehensively provides the experimental measures to improve the measurement accuracy. Then through the uncertainty evaluations of the results with different measures, this paper from a point of quantitative view proves that taking these measures can reduce the dispersion of the measurement results and significantly improve the accuracy of experimental results.
