Line 9:

\partial_j T_{ij} + f_i =\rho \, \partial_{tt} u_i

</math>

* [[constitutive equation]] (''anisotropic [[Hooke's law]]'')

<math>

T_{ij} = C_{ijkl} \, E_{kl}

Line 23:

* <math> \rho </math> is density

* <math> u_i </math> is displacement

* <math> C_{ijkl}=C_{klij}=C_{jikl}=C_{ijlk} </math> is elasticitythe [[stiffness tensor]]

* <math> E_{ij}=E_{ji} </math> is strain
