fedoo.weakform.PlateEquilibriumSI

class PlateEquilibriumSI(PlateConstitutiveLaw, name=None, space=None)

Weak formulation of the mechanical equilibrium equation for plate models. weakform.PlateEquilibrium should be prefered unless you know what you are doing: This weakform use a reduced integration to treat the shear terms. That avoid locking problems for elements with linear interpolation but may lead to instability when used with quadratic interpolations. This weak form has to be used in combination with a Shell Constitutive Law like fedoo.constitutivelaw.ShellHomogeneous or fedoo.constitutivelaw.ShellLaminate. Geometrical non linearities not implemented for now.

Parameters:

  • PlateConstitutiveLaw (ConstitutiveLaw name (str) or ConstitutiveLaw object) – Shell Constitutive Law (fedoo.constitutivelaw)

  • name (str) – name of the WeakForm
