A conservative Eulerian formulation of the equations for elastic flow (Q1115226)

The local, or Eulerian, formulation of the equations of hyperelasticity and certain relevant properties pertaining to that formulation (e.g., Signorini's remarks on the `inverse' displacement) seem to have disappeared under the more recent strata of literature. The conservative, first-order formulation has been used often in wave propagation studies. The local, conservative, first-order formulation, which the author illustrate, may be relevant for the application to high-quality numerical processes.
