Fourth Order Elastic Constants for Sodium Chloride to 270 Kbar by Wave Dynamics.

摘要

The dilatational and shear velocities and the equation of state for an isotropic material under high hydrostatic pressures by the methods of continuum mechanics using the theory of small deformation superposed on a finite strain have been derived. The strain energy density of the material is taken to fourth order in terms of the strain invariants.
