nDMaterial('ElasticOrthotropic', matTag, Ex, Ey, Ez, nu_xy, nu_yz, nu_zx, Gxy, Gyz, Gzx, rho=0.0)

This command is used to construct an ElasticOrthotropic material object.

matTag (int) integer tag identifying material
Ex (float) elastic modulus in x direction
Ey (float) elastic modulus in y direction
Ez (float) elastic modulus in z direction
nu_xy (float) Poisson’s ratios in x and y plane
nu_yz (float) Poisson’s ratios in y and z plane
nu_zx (float) Poisson’s ratios in z and x plane
Gxy (float) shear modulii in x and y plane
Gyz (float) shear modulii in y and z plane
Gzx (float) shear modulii in z and x plane
rho (float) mass density (optional)

The material formulations for the ElasticOrthotropic object are:

  • 'ThreeDimensional'
  • 'PlaneStrain'
  • 'Plane Stress'
  • 'AxiSymmetric'
  • 'BeamFiber'
  • 'PlateFiber'
