The present paper reports experimental measurements of particle velocity change at elastic-plastic shock wave fronts to estimate a hybrid numerical prediction method of particle velocity variation with shock wave propagation in metals. The elastic and plastic shock waves are generated in 6061-T6 aluminum by planer impact experiments using a single-stage light-gas gun that has 40mm muzzle diameter. Impact angles are also checked on using 4-pin-sensor system, and the particle velocity variations at the rear surface of target plates are measured by a velocity interferometer system (VISAR). High-resolution measurements on the plastic shock wave front are carried out, and detailed experimental data that are needed for evaluating the estimating simulation of the shock wave profile are obtained.
