Abstract

Experimental investigations were performed on the influence of flaws on the characteristics of an electric response of gypsum-sand specimens under impact excitation. A physico-mathematical model of an electric response to an elastic impact excitation of piezo-containing heterogeneous materials was developed. Using the apparatus of continuum mechanics, the parameters of an electric signal from a dielectric specimen exposed to a pulsed action were theoretically calculated and agreement with the experimental results was observed.
