Computer simulation of copper and silver under shock compression conditions
Source abstract
Abstract
A correction to the embedded atom method potentials for copper and silver is proposed which ensures good agreement between molecular dynamics simulation results and experimental data on the thermodynamic properties of Cu and Ag under shock compression conditions (at pressures of up to 1473 GPa in the case of copper and up to 478 GPa in the case of silver). The potentials are represented in analytical form. The calculations take into account the contributions of the valence electrons to the energy and pressure of the metals. This reduces the simulated temperature on the Hugoniot adiabat (by 30% in the case of copper and by a factor of 1.5–2 in the case of silver) relative to estimates in the Grüneisen model.
