Abstract

A complete and consistent equation of state based on Mie-Grüneisen assumptions was developed. This EOS assumes constant Gruneisen coefficient, but a variable specific heat that is modeled using Einstein's theory of heat capacities using two oscillators. The shock velocity particle velocity Hugoniot (Us-up) was derived from density functional theory molecular dynamics (DFT-MD). The EOS was formatted as a tabular EOS and checked for consistency using one-dimensional impact simulations in CTH.
