    • We eschew the term pressure and use stress (always the longitudinal component, positive in compression) noting that the magnetic stress and stress in a liquid are Isotropic, while for solids that can support shear stresses, longitudinal stress is different from the pressure.

    • note
    • Assumptions stated without further explanation: we are measuring the principal room temperature isentrope because known dissipative mechanisms are small and to within experimental uncertainty, no deviation from centered wave behavior has been seen in several metals; strength effects that destroy the pure hyperbolicity of the governing equations have no effect on results at these large strains; the interior point where the determined stress load is assumed to be applied is in fact joule heated and likely vaporized. Nonetheless, this load, applied at this location to ambient aluminum, accurately produces the stress history that is responsible for the motion that is measured at the VISAR plane.

    • This is a way of shaping the approximate stress history obtained from the backward integration. Alternatively we could have used any number of analytical forms for describing the desired stress history. A sixth-order polynomial in time would likely suffice. But the backward analysis produces a nice first guess; we started with that and multiplied by a polynomial in time, much like a perturbation calculation, to find the actual stress history.
