Paper Abstract
A method has been developed for visualizing the internal deformation fields in opaque materials during impact events using a combination of flash X-rays and digital speckle analysis. The random speckle pattern required for the digital speckle analysis is achieved by seeding the specimen with a layer of 20% coverage X-ray opaque powder, such as lead. By utilizing flash X-rays a comparison can be made of the images of the random pattern before and during an impact event using speckle pattern analysis software. This allows the displacement field to be determined.
