Abstract:
Acoustic emission activity and longitudinal and volumetric deformations in rock salt samples subjected to uniaxial mechanical loading with a constant strain rate and thermal stress are measured. The features of acoustic emission during deformation under various thermobaric experimental conditions are analyzed. It is shown that, in contrast to the deformation parameters, the change in the activity of acoustic emission at the boundaries of the indicated stages is nonmonotonic in nature, as well as features that make it possible to accurately determine each stage and estimate the elastic and strength properties of the rock salt.
Keywords:
rock salt, acoustic emission, thermobaric effect, deformation stages.
