3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Bending vibration flexuralvibration
Sample vibration in the longitudinal direction of the normal level.
3.2
Torsional Vibration torsionvibration
In the cross-sectional sample twisted around the longitudinal direction of the vibration occurs.
4 Summary of Method
Using mechanical excitation pulse excitation generated, acting on the rectangular cross-section specimens under high-temperature environment caused by vibration of the sample, measuring bend specimen
Song and torsional vibration frequency of the vibration frequency. Samples obtained by fast Fourier transform fundamental frequency, the fundamental frequency of the bending vibration use to calculate the sample
The elastic modulus, the frequency of vibration of the torsion is calculated the shear modulus. Poisson's ratio of an elastic modulus and shear modulus relationship calculated.
Note. Due to the vibration frequency of the sample group depends on the sample size, quality, and modulus of elasticity in the sample mass and dimensions known, the fundamental frequency can be measured after the meter
Calculating the modulus of elasticity. Flexural modulus of elasticity depends on the fundamental frequency of vibration, torsional shear modulus depends on the vibration frequency. Poisson's ratio of an elastic modulus of the material and
Shear modulus decision, only two of the three are independent.
5 Test System
