Displacement Maps in Taylor impact using Speckle Radiography

POSTER

Abstract

A method was developed using the small gas gun facility at the Cavendish Laboratory, (Cambridge University) to determine the internal displacement characteristics of a polymer rod undergoing asymmetric Taylor impact. Using a layer of lead filings and Digital Speckle Radiography it was possible to build up a displacement map. It is hoped that this technique could be used to derive material properties such as yield strength.
