4.1.4.13 Orthotropic Elastic

The material type for orthotropic elasticity is “orthotropic elastic”. The following material parameters must be defined:
<E1> Young's modulus in the x-direction [P]
<E2> Young's modulus in the y-direction [P]
<E3> Young's modulus in the z-direction [P]
<G12> Shear modulus in the xy-plane [P]
<G23> Shear modulus in the yz-plane [P]
<G31> Shear modulus in the xz-plane [P]
<v12> Poisson's ratio between x- and y-direction [ ]
<v23> Poisson's ratio between y- and z-direction [ ]
<v31> Poisson's ratio between z- and x-direction [ ]
The stress-strain relation for this material is given by Material axes may be specified as described in Section 4.1.1.2↑.
Example:
<material id="3" type="orthotropic elastic">
  <mat_axis type="vector">
    <a>0.866,0.5,0</a>
    <d>-0.5,0.866,0</d>
  </mat_axis>
  <E1>1</E1>
  <E2>2</E2>
  <E3>3</E3>
  <v12>0</v12>
  <v23>0</v23>
  <v31>0</v31>
  <G12>1</G12>
  <G23>1</G23>
  <G31>1</G31>
</material>
