FIELD: radio engineering, communication.
SUBSTANCE: method includes loading a sample to a given tension value in the material and measuring the propagation time of an acoustic wave in a direction perpendicular to the loading direction, wherein the sample is stretched or compressed to tension σ, which is below the proportionality limit of the material, measuring the time t1 of the propagation of the acoustic wave between two parallel surfaces of the sample, unloading the sample, respectively compressing or stretching the sample to tension σ, measuring the time t2 of the propagation of the acoustic wave between said surfaces of the sample and determining the acoustoelastic communication coefficient using a given mathematical expression.
EFFECT: high accuracy of determining the acoustoelastic communication coefficient of material.
