The Eulerian Seth-Hill elastic solid constitutive model.[^1]<sup>,</sup>[^2]
**Parameters**
- The bulk modulus $`\kappa`$.
- The shear modulus $`\mu`$.
- The exponent $`m`$.
**External variables**
- The deformation gradient $`\mathbf{F}`$.
**Internal variables**
- None.
**Notes**
- The Eulerian Seth-Hill strain measure is given by $`\mathbf{e}^{(m)} = \tfrac{1}{m}(\mathbf{V}^m - \mathbf{1})`$.
- The model reduces to the hyperelastic [Hencky model](super::super::hyperelastic::Hencky) when $`m=0`$.
- The model reduces to the elastic [Saint Venant-Kirchhoff model](super::SaintVenantKirchhoff) when $`m=2`$.
- The model reduces to the [Eulerian Almansi-Hamel model](super::AlmansiHamelEulerian) when $`m=-2`$.
- This is the Eulerian counterpart of the [Lagrangian Seth-Hill model](super::SethHillLagrangian).
