摘要: A laser-produced x-ray drive was used to shocklessly compress solid aluminum a peak longitudinal stress of 110 GPa within 10 ns. Interface velocities versus time for multiple sample thicknesses were measured and converted density (Px-rho) using an iterative Lagrangian analysis. These are the fastest shockless compression Px(rho) results reported date, stiffer than models that have been benchmarked against both static shock-wave experiments. The present suggest at these short scales there is higher stress-dependent strength time-dependent inelastic response had expected.
