Computes reduced strain vector in given integration point, generated by internal processes in material, which are independent on loading in particular integration point.

Default implementation takes into account temperature induced strains and eigenstrains.

Parameters

answer	Returned strain vector.
gp	Integration point.
tStep	Time step (most models are able to respond only when tStep is current time step).
mode	Determines response mode (Total or incremental).

Todo:: Hack for loose gausspoints. We shouldn't ask for "gp->giveElement()". FIXME

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.

void oofem::LatticeDamage2d::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).

MaterialStatus * oofem::LatticeDamage2d::giveStatus ( GaussPoint * gp ) const

virtual

Returns material status of receiver in given integration point.

If status does not exist yet, it is created using CreateStatus member function.

Parameters

gp	Returns reference to material status belonging to integration point gp.

Returns: Material status associated with given integration point.

	)

virtual

Computes the stiffness matrix for giveRealStressVector of receiver in given integration point, respecting its history.

The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result.

Parameters

answer	Contains result.
mode	Material response mode.
gp	Integration point.
tStep	Time step (most models are able to respond only when tStep is current time step).

Returns a vector of coefficients of thermal dilatation in direction of each material principal (local) axis.

Parameters

answer	Vector of thermal dilatation coefficients.

IRResultType oofem::LatticeDamage2d::initializeFrom ( InputRecord * ir )

virtual

Initializes receiver according to object description stored in input record.

This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record.
