Energy Spectrum of Acoustic Emission Signals in Complex Media
Abstract
A model of the energy spectrum of acoustic emission signals in complex structures with internal degrees of freedom is proposed. On the basis of the computational experiment of X-ray diffraction data, a quantum mechanical calculation of the applicability of the model of a complex medium initiating the formation of acoustic emission signals was performed. The translational and rotational invariance of energy in the energy spectrum of acoustic emission signals of media with a complex structure is established. The presented model of the energy spectrum of acoustic emission signals makes it possible to determine the separate contribution of the low-frequency and high-frequency components of the energy spectrum of acoustic emission signals in media of complex structure.
