fedoo.constitutivelaw.BeamProperties

class BeamProperties(material, A, Jx, Iyy, Izz, k=0, name='')

__init__(material, A, Jx, Iyy, Izz, k=0, name='')

Beam properties constitutive law.

This constitutive law should be associated with the weakform fedoo.weakform.BeamEquilibrium

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 modulus and the shear modulus (as fedoo.constitutivelaw.ElasticIsotrop).

• A (scalar or arrays of gauss point values) – Beam section area.

• Jx (scalar or arrays of gauss point values) – Torsion constant.

• Iyy (scalar or arrays of gauss point values) – Second moment of area with respect to y (beam local coordinate system).

• Izz (scalar or arrays of gauss point values) – Second moment of area with respect to z (beam local coordinate system).

• k (scalar or arrays of gauss point values, default: 0) – Shear shape factor. If k=0 (default) the beam use the bernoulli hypothesis.

• name (str) – name of the WeakForm.
