Methods associated with the First PK stress tensor.

Computes the first Piola-Kirchhoff stress vector for given total deformation gradient and integration point.

The total deformation gradient is computed directly from displacement field at the given time step. 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. The First Piola-Kirchhoff stress vector is computed in Total Lagrangian mode

Detailed Description

Abstract base class for all "structural" constitutive models.

Todo:: Update documentation

It declares common services provided by all structural material models. The implementation of these services is partly left on derived classes, which will implement constitutive model dependent part. Some general purpose services are implemented on this level. For details, how to store material model related history variables in integration points, see base class Material documentation.

The constitutive model can in general support several material modes (plane stress, plane strain ,... modes). Its capabilities can be examined using hasMaterialModeCapability service. It is generally assumed, that results obtained from constitutive model services are according to valid material mode. This mode is determined from integration point, which is compulsory parameter of all material services. Structural material introduces several stress/strain modes. Full and reduced formats of stress/strain vectors are introduced for convenience. The full format includes all components, even if they are zero due to stress/strain mode nature, but in the reduced format, only generally nonzero components are stored. (full format must used only if absolutely necessary, to avoid wasting of space. It is used by output routines to print results in general form). Methods for converting vectors between full and reduced format are provided.

If in particular mode particular stress component is zero, the corresponding strain is not computed and not stored in reduced vector, and in full vector there is zero value on corresponding position. On the other hand, if some zero strain is imposed, On the other hand, if zero strain component is imposed this condition must be taken into account in geometrical relations (at element level), and corresponding component are included stress/strain reduced vectors.

Structural material introduces following basic stress/strain modes

3d state - all components of general stress/strain vector are generally nonzero. General 3d strain vector has following components {sig_xx, sig_yy, sig_zz, tau_yz, tau_xz, tau_xy}
plane stress - sig_zz = tau_yz = tau_xz = 0.
plane strain - eps_z = gamma_xz = gamma_yz = 0. 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.
1d uniaxial state - sigma_y = sigma_z = tau_yz = tau_zx = tau_xy = 0.
2d beam layer - sigma_y=sigma_z=tau_zy=tau_xy = 0.
3d shell layer, 2d plate layer - sigma_z = 0.

Derived classes can of course extend those modes. Generally speaking, there are following major tasks, covered by declared services.

Computing real/second PK stress vector (tensor) at integration point for given strain increment and updating its state (still temporary state, after overall equilibrium is reached).
Updating its state (final state), when equilibrium has been reached.
Returning its material stiffness (and/or flexibility) matrices for given material mode.
Storing/restoring its context to stream.
Returning its material properties.

Structural material services should not be called directly by elements. Instead, they always should pass their requests to corresponding cross section model. Cross section performs all necessary integration over its volume and invokes material model services.

void oofem::StructuralMaterial::givePlaneStrainStiffMtrx	(	FloatMatrix &	answer,
		MatResponseMode	mmode,
		GaussPoint *	gp,
		TimeStep *	tStep
	)

virtual

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).

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

virtual

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).

int oofem::StructuralMaterial::giveVoigtSymVectorMask	(	IntArray &	answer,
		MaterialMode	mmode
	)

static

The same as giveVoigtVectorMask but returns a mask corresponding to a symmetric second order tensor.

Returns a mask of the vector indicies corresponding to components in a symmetric second order tensor of some stress/strain/deformation measure that performes work. Thus, components corresponding to imposed zero stress (e.g. plane stress etc.) are not included. On the other hand, if zero strain components are imposed( e.g. plane strain etc.) this condition must be taken into account in geometrical relations. Therefore, these corresponding components are included in the reduced vector. Which compnents to include are given by the particular MaterialMode. Ex: PlaneStress -> [1 2 6]

Parameters

answer	Returned mask.
mmode	Material response mode.

Returns: The number of components in the corresponding full vector.

Todo:: This isn't actually fixed yet. Should be made compatible with 3dShell and 2dBeam

Returns a mask of the vector indicies corresponding to components in a general (non-symmetric) second order tensor of some stress/strain/deformation measure that performes work.

Thus, components corresponding to imposed zero stress (e.g. plane stress etc.) are not included. On the other hand, if zero strain components are imposed( e.g. plane strain etc.) this condition must be taken into account in geometrical relations.
