Method for computing 1d stiffness matrix of receiver. Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to 1d stiffness using reduce method described above. However, this reduction is quite time consuming and if it is possible, it is recommended to overload this method and provide direct method for computing particular stiffness matrix.

Parameters

mmode	Material response mode.
gp	Integration point, which load history is used.
tStep	Time step (most models are able to respond only when tStep is current time step).

Returns: Stiffness matrix.

FloatMatrixF< 3, 3 > oofem::PlasticMaterial::giveFiberStiffMtrx	(	MatResponseMode	mmode,
		GaussPoint *	gp,
		TimeStep *	tStep ) const

overrideprotectedvirtual

Method for computing 1d fiber stiffness matrix of receiver. Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to 1d fiber stiffness using reduce method described above. However, this reduction is quite time consuming and if it is possible, it is recommended to overload this method and provide direct method for computing particular stiffness matrix.

Parameters

answer	Stiffness matrix.
mmode	Material response mode.
gp	Integration point, which load history is used.
tStep	Time step (most models are able to respond only when tStep is current time step).

Returns the integration point corresponding value in Reduced form.

Parameters

answer	Contain corresponding ip value, zero sized if not available.
gp	Integration point to which the value refers.
type	Determines the type of internal variable.
tStep	Determines the time step.

Returns: Nonzero if the assignment can be done, zero if this type of variable is not supported.

FloatMatrixF< 4, 4 > oofem::PlasticMaterial::givePlaneStrainStiffMtrx	(	MatResponseMode	mmode,

overrideprotectedvirtual

Method for computing plane strain stiffness matrix of receiver. Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to plane strain stiffness using reduce method described above. However, this reduction is quite time consuming and if it is possible, it is recommended to overload this method and provide direct method for computing particular stiffness matrix. Note: as already described, if zero strain component is imposed (Plane strain, ..) this condition must be taken into account in geometrical relations, and corresponding component has to be included in reduced vector. (So plane strain conditions are \( \epsilon_z = \gamma_{xz} = \gamma_{yz} = 0 \), but relations for \( \epsilon_z\) and \(\sigma_z\) are included).

Parameters

answer	Stiffness matrix.
mmode	Material response mode.
gp	Integration point, which load history is used.
tStep	Time step (most models are able to respond only when tStep is current time step).

◆ giveRealStressVector()

void oofem::PlasticMaterial::giveRealStressVector	(	FloatArray &	answer,
		GaussPoint *	gp,
		const FloatArray &	reducedStrain,
		TimeStep *	tStep ) const

overridevirtual

Computes the real stress vector for given total strain and integration point. The total strain is defined as strain computed directly from displacement field at given time. The stress independent parts (temperature, eigenstrains) are subtracted in constitutive driver. The service should use previously reached equilibrium history variables. Also it should update temporary history variables in status according to newly reached state. The temporary history variables are moved into equilibrium ones after global structure equilibrium has been reached by iteration process.

Parameters

answer	Stress vector in reduced form. For large deformations it is treated as the second Piola-Kirchoff stress.
gp	Integration point.
reducedStrain	Strain vector in reduced form. For large deformations it is treated as the Green-Lagrange strain.
tStep	Current time step (most models are able to respond only when tStep is current time step).
