[SIT22-02] Towards constitutive equations for the deep Earth
Keywords:Deep Earth physical properties, Bulk modulus, Shear modulus
However, by working with invariants of the stretch tensor suitable isotropic constitutive equations can be found that add-in shear properties in a consistent way via local representations about a pre-stressed state. Such constitutive relations are particularly useful for high-pressure phases in the deep Earth, and make only slight modifications to popular representations for the bulk modulus.
