fedoo.constitutivelaw.BeamCircular

class BeamCircular(material, r, k=0.9, name='')

__init__(material, r, k=0.9, name='')

Properties for a beam with circular cross section.

Parameters:

• material (ConstitutiveLaw name (str) or ConstitutiveLaw object) – Material Constitutive Law used to get the elastic modulus and shear modulus. The ConstitutiveLaw object should have attributes E and G that gives the young and the shear modulus (as fedoo.constitutivelaw.ElasticIsotrop).

• r (scalar or arrays of gauss point values) – Radius of the beam section.

• k (scalar or arrays of gauss point values, default: 0.9) – Shear shape factor. If k=0 the beam use the bernoulli hypothesis. Default is set to 0.9 (usual value for cylindrical beam).

• name (str) – Name of the WeakForm.
