Shock Hugoniots based on the self-consistent average atom (SCAA) model. Theory and experiments. (Second revision)

Abstract

We use a “self-consistent average atom” (SCAA) model to compute shock Hugoniots for aluminum, iron, molybdenum, strontium, barium and thulium. The pressures and energies include relativistic effects. We make comparisons with the Thomas-Fermi-Dirac (TFD) model and with the available experimental data including pressures, shock and particle speeds and energy deposition. The connection between the usage of the “average atom” (AA) model and “detailed configuration accounting” (DCA) is discussed in the Appendix.
