ABSTRACT:
The method of measuring dynamic characteristics of materials consists in obtaining, in the course of measurement, a control current which ensures oscillations of a specimen of a material at a preset amplitude and frequency. Then, real and imaginary components of the control current are discriminated, and two restoring currents are generated; these currents are summated, and the total current is used to control the movement of the specimen; after that, the real and imaginary components of the control current are discriminated for the second time, and their value, as well as the values of the restoring currents and the preset amplitude and frequency of the deformation of the specimen are used to calculate dynamic characteristics of the material.
