Abstract
Symmetric Taylor impacts of copper and RHA rods were performed using a light gas gun. High-speed photography was used in back illumination to obtain silhouette sequences of the deforming rods. Predictions were then made of the rod profiles using an Armstrong-Zerilli path-dependent model within a Lagrangian finite element code. These predictions were then compared with the experiments and excellent agreement found for both materials.
