Detailed Description

Simple isotropic damage based model for 2d interface elements. In 2d, the interface elements are used to model contact layer between element edges. The generalized strain vector contains two relative displacements (in normal and shear direction). The generalized stress vector contains corresponding tractions in normal and tangent direction.

The behaviour of the model is elastic, described by normal and shear stiffness components. Isotropic damage is initiated when the stress reaches the tensile strength. Damage evolution is governed by normal component of generalized strain vector (normal relative displacement) by an exponential softening law.

◆ ExpCZMaterial()

oofem::ExpCZMaterial::ExpCZMaterial	(	int	n,

Member Function Documentation

◆ checkConsistency()

int oofem::ExpCZMaterial::checkConsistency ( void )

overridevirtual

Allows programmer to test some internal data, before computation begins. For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns: Nonzero if receiver is consistent.

Reimplemented from oofem::FEMComponent.

Definition at line 136 of file expczmaterial.C.

◆ CreateStatus()

MaterialStatus * oofem::ExpCZMaterial::CreateStatus ( GaussPoint * gp ) const

inlineoverridevirtual

Creates new copy of associated status and inserts it into given integration point.

Parameters

gp	Integration point where newly created status will be stored.

Returns: Reference to new status.

Reimplemented from oofem::Material.

Definition at line 121 of file expczmaterial.h.

◆ giveClassName()

const char * oofem::ExpCZMaterial::giveClassName ( ) const

inlineoverridevirtual

Returns: Class name of the receiver.

Implements oofem::FEMComponent.

void oofem::ExpCZMaterial::giveEngTraction_3d	(	FloatArray &	answer,
		GaussPoint *	gp,
		const FloatArray &	jump,
		TimeStep *	tStep )

override

Todo: only study normal stress for now

◆ giveIPValue()

int oofem::ExpCZMaterial::giveIPValue	(	FloatArray &	answer,
		GaussPoint *	gp,
		InternalStateType	type,
		TimeStep *	tStep )

overridevirtual

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.

Definition at line 105 of file expczmaterial.C.

References oofem::Material::giveStatus().

◆ initializeFrom()

void oofem::ExpCZMaterial::initializeFrom ( InputRecord & ir )

overridevirtual

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. Note that initializeFrom may be called mutiple times.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.
priority	Priority of the input record. This is used to determine the order of initialization

void oofem::ExpCZMaterial::printYourself ( )

overridevirtual

Prints receiver state on stdout. Useful for debugging.
