Abstract

A study of the response of a heterogeneous material (stivlon) to a short pressure pulse reveals a qualitatively new effect: the onset of oscillatory precursors of the main pressure pulse when the concentration of a filler randomly distributed in a binder material exceeds a threshold value. The mechanism for the onset and propagation of these precursors is investigated on the basis of a cluster model. The results of a numerical simulation are compared with the experimental data.
