Elastic isotropic material properties container.

Stores material properties for elastic wave propagation in isotropic solids. Supports both elastic and viscoelastic media types through template specialization with SFINAE (enable_if constraint).

Material parameters:

  • kappa: Bulk modulus (resistance to compression)

  • mu: Shear modulus (resistance to shear deformation)

  • rho: Density (mass per unit volume)

DATA_CONTAINER macro for details on generated members and methods.

Template Parameters:

  • DimensionTag – Spatial dimension (dim2/dim3)

  • MediumTag – Physical medium type (elastic, elastic_sh, elastic_psv)

  • c33, c35: Elastic stiffness tensor components (row 3)

  • c55: Elastic stiffness tensor component (shear)

  • c12, c23, c25: Additional stiffness tensor components

  • rho: Density (mass per unit volume)
