fedoo.weakform.InterfaceForce

class InterfaceForce(constitutivelaw, name='', nlgeom=False, space=None)

Weak formulation of the interface equilibrium equation.

• Require an interface constitutive law such as fedoo.constitutivelaw.CohesiveLaw or fedoo.constitutivelaw.Spring

• Geometrical non linearities not implemented

Parameters:

• constitutivelaw (str or ConstitutiveLaw) – Interface constitutive law (ConstitutiveLaw object or name) (fedoo.constitutivelaw)

• name (str, optional) – name of the WeakForm

• nlgeom (bool (default = False)) – For future development If True, return a NotImplemented Error

__init__(constitutivelaw, name='', nlgeom=False, space=None)
