fedoo.constitutivelaw.FE2

class FE2(assemb, name='')

FE² constitutive law based on periodic microscopic problems.

A microscopic finite-element problem is solved at each macroscopic integration point. The macroscopic strain is prescribed through the problem-level MeanStrain degrees of freedom created by PeriodicBC.

Parameters:

• assemb (Assembly, str, or list of Assembly) – Microscopic assembly, its registered name, or one microscopic assembly per macroscopic integration point.

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

__init__(assemb, name='')

Methods

FE2.get_H_plane_stress(H)	Convert a full 3D tangent matrix H in an equivalent behavior in 2D with the plane stress assumption.
FE2.get_all()	Return a dict with all the known ConstitutiveLaw (with a name).
FE2.initialize(assembly, pb)	Initialize the constitutive law for the current problem.
FE2.local2global_H(H)	Rotate stiffness matrix from local material frame to global frame.
FE2.reset()	Reset the constitutive law.
FE2.set_density(density)	Set the mass density associated with this mechanical material.
FE2.set_start(assembly, pb)	Begin a new time iteration.
FE2.to_start(assembly, pb)	Restart the current time iteration.
FE2.update(assembly, pb)	Update the constitutive law for the current problem state.

FE2.name	Name of the constitutive law.
FE2.is_initialized	Tag set to True once the law is intialized.
