Abstract

The measurements of intensity of infrared radiation from the surface of rock sample under nonstationary change in stress state are described. The synchronized records of alterations in axial stress of sample under the uniaxial compression and the corresponding time variations in the intensity of infrared radiation from the sample surface are obtained. It is shown that identification of the parameters of elastic oscillations under the action of nonstationary load is reliable.
