EXPERIMENTAL METHOD FOR DIFFRACTION STUDIES DURING IMPACT.

Abstract

A new experimental system and method has been developed to determine the large axial strains, strain-rates, and the wave velocities associated with individual strain levels during axial impact at velocities to several thousand feet per second. The system employs in-surface diffraction grating strain transducers illuminated by a pulsed ruby laser, with the time-dependent diffraction pattern recorded by a high speed streak camera. (Author)
