Determination оf coefficient of elasticity of the material on the base of Fourier transformation of acoustic vibrations of the sample

The hardware and software of the unit for determination оf the coefficient of elasticity of the material is described. The unite is based on the measurement of resonance frequency of acoustic vibrations, which is caused by pulsing mechanical impact. Acoustic vibrations are recorded in high frequency range in the computer memory and then Fourier transformation is executed. The resonance frequency is defined with the help of the signal after Fourier transformation, and then coefficient of elasticity is calculated.
