fedoo.constitutivelaw.BeamRectangular

class BeamRectangular(material, a, b=None, k=0.8333333333333334, name='')

__init__(material, a, b=None, k=0.8333333333333334, name='')

Properties for a beam with rectangular 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).

• a (scalar or arrays of gauss point values) – Dimension of the beam section along the local y axis.

• b (scalar or arrays of gauss point values, optional) – Dimension of the beam section along the local z axis. If b is not specified, a square section is assumed.

• k (scalar or arrays of gauss point values, default: 5/6) – Shear shape factor. If k=0 the beam use the bernoulli hypothesis. Default is set to 5/6 (usual value for rectangular beam).

• name (str) – Name of the WeakForm.
