Determination of Young's modulus of ceramics from flexural vibration at elevated temperatures.

Popis výsledku v původním jazyce

In this paper we describe the construction of a laboratory-made resonant apparatus for the modulated force thermomechanical analysis (mf-TMA) and estimate the uncertainty of the measurement of Young's modulus of a porcelain sample. The porcelain sample was measured while increasing the temperature up to 1000 °C/5 °Cmin-1. Thermodilatometry was performed to determine the actual dimensions of the sample in the same temperature regime. We assessed the influence of the repeatability of the directly measuredvalues, the accuracy of the used measurers and different exceptions from the ideal experimental arrangement on the Young's modulus measurement uncertainties of types A and B. We found that the majority of the total uncertainty (80 %) is determined at the room temperature. The remaining sources of uncertainty can be attributed to thermal expansion of the sample and inhomogeneity of the temperature field. The relative expanded uncertainty of the Young's m
