The Study of Equipment for Testing High Temperature Elastic Modulus Based on the Acoustical Resonance Method

Abstract:

A self-designed testing device for high-temperature elastic modulus was developed based on the principle of acoustical resonance, having great accuracy and repeatability. Experiment was made to test the elastic modulus of two kinds of glass. The experimental data showed that compared with normal glass, Al₂O₃•SiO₂ glass was the 1.2 times the value of elastic modulus of normal glass and had greater stability than normal glass in high temperature. The softening point temperatures of Al₂O₃•SiO₂ glass and normal glass were respectively 600°C and 400°C. The self-designed testing device was able to estimate the property of glass.
