An Experimental Investigation of Late-Stage Equivalence for the Axial Hypo- and Hypervelocity Impact of Rods

Abstract

This report describes the development of a diffraction-grating strain-measurement system capable of measuring axial surface strains in target rods experiencing axial hypo- and hypervelocity impact and its subsequent application to evaluate the existence of the late-stage equivalence principle for this impact configuration.
