Abstract

The amplitude-frequency characteristics of electric responses to elastic impact excitations of building materials were investigated. It was established that the frequencies of the main spectral peaks of electric signals are determined by the impact duration, dimensions of a specimen, and velocities of longitudinal and transverse acoustic vibrations. The ratio of the magnitudes of these spectral peaks is determined by the spectrum of the impact excitation, the shapes of articles, and the geometries of the testing experiments.
