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>
