| Abstract Scope |
Knowledge of the Hugoniot Elastic Limit (HEL) is essential for understanding the dynamic behavior of materials subjected to impact environments, such as in geophysics, aerospace, and defense applications. Conventional methods for determining the HEL, although requiring only a fraction of a second for the actual experiment, take several hours in terms of set-up time. In this work, a high-throughput test methodology is presented for HEL measurements, based on laser-shock coupled with computer vision and automation. We demonstrate the approach by determining the HEL for Cu and INVAR, as a first step towards adapting the technique broadly to structural materials. The limitations and potential of this approach are discussed. |
