fedoo.constitutivelaw.CompositeUD

class CompositeUD(Vf=0.6, E_f=250000, E_m=3500, nu_f=0.33, nu_m=0.3, angle=0, name='')

Linear Orthotropic constitutive law defined from composites phase parameters, assuming uniform unidirectional fibers. The fiber are assumed in the X direction. Use Change of basis to rotate the material. The constitutive Law should be associated with fedoo.weakform.InternalForce

Parameters:

  • Vf (scalar or arrays of gauss point values.) – Fiber volume fraction

  • E_f (scalar or arrays of gauss point values.) – Fiber Young modulus

  • E_m (scalar or arrays of gauss point values.) – Matrix Young modulus

  • nu_f (scalar or arrays of gauss point values.) – Fiber Poisson Ratio

  • nu_m (scalar or arrays of gauss point values.) – Matrix Poisson Ratio

  • angle (scalar or arrays of gauss point values (default=0)) – The angle of the fibers relative to the X direction normal to the Z direction (if defined, the local material coordinates are used)

  • name (str, optional) – The name of the constitutive law
