“…The present results are also basically consistent with the MD results of us=5.53292+1.21337up obtained by the multiscale shock technique (MSST) for the aluminum single crystal [7]. The pressure during shock compression for the NC aluminum deviates from the existing experimental values [21,22] and MD results [23] for aluminum single crystal, as shown in Fig. 4.…”

The characteristics of shocked nanocrystalline aluminum are investigated by using molecular dynamics method based on the embedded atom method potential function. The result presents the particle velocity profile and the width of shock front in detail. The simulated Hugoniot relations are basically consistent with the experimental data and other molecular dynamics results. The width of shock front decreases with the particle velocity exponentially.

“…Considering the uncertainty of the experiment, and the impact velocity of our subsequent nanoparticle collision simulation is less than 3000 m/s, we believe that the 2NN-MEAM potential of Al and Ni still has good accuracy under strong impact loads, so the 2NN-MEAM potential is used for subsequent collision simulation.

Molecular dynamic simulations have been performed to explore contact behavior, microstructure evolution and sintering mechanism of Al‐Ni dissimilar nanoparticles under high‐velocity impact. We confirmed that the simulated contact stress, contact radius, and contact force under low‐velocity impact are in good agreement with the predicted results of the Hertz model. However, with increasing the impact velocity, the simulated results gradually deviate from the predicted results of the Hertz model due to the elastic‐plastic transition and atomic discrete structure. The normalized contact radius versus strain exhibits a weak dependence on nanosphere diameter. Below a critical velocity, there are very few HCP atoms in the nanospheres after thermal equilibrium. There are two different sintering mechanisms: under low‐velocity impact, the sintering process relies mainly on the dislocation slip of Al nanospheres, while the dislocation slip of Ni nanospheres and the atomic diffusion of Al nanospheres predominate under high‐velocity impact.
