Abstract: Different embeded-atom method potentials of gold were used in molecular dynamics simulation for shocked solid gold. Comparison between the simulation results and the experiment data of Hugoniot state for gold has been carried out. The potentials whose corresponding simulating shocked Hugoniot data are consistent with theoretical prediction were used in subsequent foamed gold simulations. The initial configuration of foamed gold has been constructed by means of randomly accumulating sphere shells in the simulation box. Three kinds of configuration have been obtained via changing the thickness, outer-radius of the sphere shell and potentials. Hugoniot states of porous polycrystal gold with 3-dimensional nanostructure under shock compression have been simulated by means of molecular dynamics(MD) method. Comparison between simulated results with porous equation of state(EOS) model and existing EOS database for Au has been done. The discrepancy suggests that experiments for the state of porous gold are necessary to verify the theory and the simulation method for porous gold.
