Аннотация:Measurements of decay of the elastic precursor wave are used to determine the initial plastic strain rate as a function of stress. Last years we performed multiple series of experiments of such kind with metals and alloys, ceramics, and glasses. In the course of these measurements we observed several unexpected effects which have not got exhaustive explanations yet. In this paper we summarize these observations with the goal to stimulate deeper analysis of the wave dynamics in relaxing media.
