FIELD: measurement of relaxation of strain of soft composites.
SUBSTANCE: samples of soft composites are positioned in heating chamber and deformed for a given value. Then on the side of one clamp, mounted and held on resonator plate of mechanical oscillations generator, to sample concurrently applied are transverse oscillations of sound frequency and heat effect by steam environment, and on basis of measured values of system of parameters of oscillations of other clamp of sample, mounted on resilient base, kinetics of strain relaxation is calculated by means of a microprocessor unit.
EFFECT: broader functional capabilities, higher precision.
