Member Function Documentation

◆ getAnisotropic()

virtual double sel::ISELShell::getAnisotropic	(	int	p,
		int	t
	)		const

pure virtual

Returns a anisotropic material property. If the shell does not have anisotropic property, this function return 0.0
. Valid values for parameter p(material-coefficient stiffness) are: 0 (C11), 1(C12) , 2 (C13), 3(C22), 4(C23) and 5(C33)
Valid values for parameter t are: 1 (membrane) and 2 (bending)

◆ getCouplingStress()

virtual double sel::ISELShell::getCouplingStress	(	const ISELNode *	node,
		bool	norm,
		uint32	side
	)		const

pure virtual

Shell-type sels: Returns the stress in coupling springs at nd_idx and side.
If norm is true, returns normal stress, else returns shear stress.
Valid values for nd_idx are 0, 1 or 2.
Valid values for side are 0 (side 1) or 1 (side 2).
The computation is general and will work even if link assignments have been modified. Computes stress based on forces in all deformable directions of link at side.

◆ getElasticStressBounds()

virtual double sel::ISELShell::getElasticStressBounds ( const bool minimum ) const

pure virtual

Returns the yield state for geogrids and liners: 0 = "No Yield" 1 = "Yielding Now" 2 = "Yield in Past"

◆ getElementStresses()

virtual void sel::ISELShell::getElementStresses	(	DVect3 *	memb,
		DVect3 *	bend
	)		const

pure virtual

Returns membrane stress resultants Nx,Ny,Nxy (parameter memb) and bending stress resultants Mx,My,Mxy (parameter bend) for ONE ISOLATED element, in its local coordinate system: average stress resultants computed on each node, based on forces acting on it.

◆ getIsotropic()

virtual double sel::ISELShell::getIsotropic ( int propNo ) const

pure virtual

Returns an isotropic material property
. Valid values for parameter propNo are: 1(Young's modulus) and 2(Poisson's ratio)

◆ getMaterialPropertyType()

virtual MaterialPropertyType sel::ISELShell::getMaterialPropertyType ( ) const

pure virtual

Returns material property type
Return values are: 1 (isotropic), 2 (orthotropic), 3 (anisotropic)

◆ getOrthotropic()

virtual double sel::ISELShell::getOrthotropic	(	int	p,
		int	t
	)		const

pure virtual

Returns a orthotropic material property. If the shell does not have orthotropic property, this function return 0.0
. Valid values for parameter p(material-coefficient stiffness) are: 0 (C11), 1(C12) , 2 (C22) and 3(C33)
Valid values for parameter t are: 1 (membrane) and 2 (bending)

◆ getPrinStress()

virtual DVect3 sel::ISELShell::getPrinStress	(	uint	index,
		quint32	locCode
	)		const

pure virtual

Returns the principal stress at location locCode.
Valid values for parameter locCode are: 0(centroid), 1(node-1) ,2 (node-2) and 3(node-3)

◆ getStress()

virtual SymTensor sel::ISELShell::getStress	(	uint	index,
		quint32	locCode
	)		const

pure virtual

Returns the symetric stress tensor at locacion locCode. Stresses are expressed in the global system.
The stresses are recovered at the current depth factor.
Valid values for parameter locCode are: 0(centroid), 1(node-1) ,2 (node-2) and 3(node-3)

◆ getStressResultant2()

virtual double sel::ISELShell::getStressResultant2	(	uint	index,
		quint32	locCode,
		quint32	component
	)		const

pure virtual

Returns the stress resultant at location locCode.
Valid values for parameter locCode are: 0(centroid), 1(node-1) ,2 (node-2) and 3(node-3) valid values for parameter component are: 0(Mx), 1(My), 2(Mxy), 3(Nx), 4(Ny), 5(Nxy), 6(Qx) and 7(qy)

◆ setIsotropic()

virtual void sel::ISELShell::setIsotropic	(	const double &	v,
		int	propNo
	)

pure virtual

Set an isotropic material property
. Valid values for parameter propNo are: 1(Young's modulus) and 2(Poisson's ratio)
