Shock-Induced Electrical Signals with Positive and Negative Components

摘要

Shock-induced electrical signals from polyethylene were examined within the framework of the Allison polarization theory, and have been found to consist of both positive and negative components. The similarity to certain shock-induced electrical signals from alkali halide crystals is noted, and hypothetical signals were calculated to display the basic features of a few alkali halide signals selected from the literature. The calculations suggest that signal profiles may not provide a clear indication of shock-wave transit time when both positive and negative components are present. (Author)
