fedoo.constitutivelaw.ElasticOrthotropic

class ElasticOrthotropic(Ex, Ey, Ez, Gyz, Gxz, Gxy, nuyz, nuxz, nuxy, name='')

Linear Orthotropic constitutive law defined from the engineering coefficients in local material coordinates.

The constitutive Law should be associated with fedoo.weakform.InternalForce

Parameters:

  • EX (scalars or arrays of gauss point values) – Young modulus along the X direction

  • EY (scalars or arrays of gauss point values) – Young modulus along the Y direction

  • EZ (scalars or arrays of gauss point values) – Young modulus along the Z direction

  • GYZ (scalars or arrays of gauss point values) – Shear modulus

  • GXZ (scalars or arrays of gauss point values) – Shear modulus

  • GXY (scalars or arrays of gauss point values) – Shear modulus

  • nuYZ (scalars or arrays of gauss point values) – Poisson’s ratio

  • nuXZ (scalars or arrays of gauss point values) – Poisson’s ratio

  • nuXY (scalars or arrays of gauss point values) – Poisson’s ratio
