3 Terms and definitions

The following terms and definitions as defined in GB/T 10623-2008 and GB/T 22315-2008 apply to this document. 3.1 elastic modulus elasticitymodulus The ratio of stress to corresponding strain below the proportional limit. Note. The elastic modulus is also called Young's modulus. [Source. GB/T 10623-2008, 2.9, with modifications] 3.2 Resonance frequencyresonancefrequency The vibration frequency of the external forcing force that causes the specimen to resonate. [Source. GB/T 22315-2008,3.2.5]

4 Principles

By subjecting the sample to longitudinal vibration excitation by acoustic waves, the sample is caused to vibrate mechanically. When the resonant frequency of the sample is the same as the excitation frequency, the sample is vibrated mechanically. Resonance occurs. The elastic modulus can be calculated by measuring the resonant frequency, length and density of the sample. ...
