fedoo.weakform.InterfaceForce

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

Weak formulation of the interface equilibrium equation.

Parameters:

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

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

  • nlgeom ({None, bool, "UL"}, optional) – Geometrical-nonlinearity formulation. If None (default), use the value defined by the associated problem. True and "UL" select the updated-Lagrangian formulation. Total Lagrangian ("TL") is not implemented for interface forces.
