Measuring the Submicrosecond Response of Shock Loaded Materials

Abstract
Methods for high precision transient measurements using simple techniques for instrumentation and target alignment are described. Techniques are discussed in terms of application to a gas gun used to study the response of materials to dynamic loading. Results indicate that tilts of about 0.01° between impacting surfaces, projectile velocity measurements to about 0.1%, and time correlations to within 0.01 μsec are readily obtainable.
