3D-DIC Analysis of a Metal Specimen Following an Impact Compression Test by the Hopkinson Bar Method

A compression after impact test by the Hopkinson bar method, which is an impact testing method, was conducted on a metal specimen. By performing 3D digital image correlation (DIC) analysis using the recorded images, the strain distribution on the surface of the specimen was visualized. In order to conduct a 3D-DIC analysis of an impact test, high-speed cameras that have a high recording speed and high resolution while also capable of synchronized recording from two directions are necessary. Satisfying all these requirements, the HPV-X2 is the optimal high-speed video camera for 3D-DIC analyses of impact tests.
