We present the analytic form of the principal Hugoniot at all pressures. It is constructed by
interpolating smoothly between three pressure (P) regimes. Specifically,(i) the low-P regime …

Although they are polymorphic (multiphase) materials, both copper and silver are reliable
Hugoniot standards, and thus it is necessary to establish an accurate analytic model of their …

Achieving ultrahigh shock pressures is straightforward. Determining the state achieved in a
Hugoniot experiment or in some other experiment on the Hugoniot to measure a physical …

The principal Hugoniot jump relations can be cast in a differential form that relates the
Grüneisen constant, isentropic bulk modulus, pressure, particle velocity, and shock velocity …

A thermodynamic equation of state (EOS) is derived which is appropriate for investigating
the thermodynamic variations along isobaric paths. By using this EOS, a Hugoniot EOS …

It has been traditional to use the fluid approximation when using solid Hugoniot data to
construct a constitutive equation for the pressure as a function of volume and energy. The …

An empirical equation of state is proposed for accurate extrapolation of high-pressure shock
Hugoniot states to other thermodynamic states. The proposed equation of state …

Hydrodynamic flow of materials, initiated by shock waves, is determined by their equation of
state (EOS). For comparatively weak shocks, the zero-temperature isotherm and thermal …

Plate impact experiments are a powerful tool in equation of state development, but are
inherently limited by the range of impact velocities accessible to the facility. In an effort to …

This study compares five methods to compute Hugoniots for porous materials, with
experimental data for porous copper. The methods compare well when porosities are low …
