Abstract

Defects of different types and sizes in a material are shown to result in variations in the spectral characteristics of electric responses to pulsed mechanical excitation of heterogeneous materials. General regularities reside in an increase in the size and concentration of defects that yields a decrease in the magnitude and quality factor of the principal spectral maximum and variations in the spectral composition of the electric response.
