◆ CreateStatus()

std::unique_ptr< MaterialStatus > oofem::CohesiveInterfaceMaterial::CreateStatus ( GaussPoint * gp) const
inlineoverridevirtual

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

Parameters
gpIntegration point where newly created status will be stored.
Returns
Reference to new status.

Reimplemented from oofem::Material.

Definition at line 89 of file cohint.h.

◆ giveClassName()

const char * oofem::CohesiveInterfaceMaterial::giveClassName ( ) const
inlineoverridevirtual
Returns
Class name of the receiver.

Implements oofem::FEMComponent.

◆ giveInputRecord()

void oofem::CohesiveInterfaceMaterial::giveInputRecord ( DynamicInputRecord & input)
overridevirtual

Setups the input record string of receiver.

Parameters
inputDynamic input record to be filled by receiver.

Reimplemented from oofem::FEMComponent.

◆ giveInputRecordName()

const char * oofem::CohesiveInterfaceMaterial::giveInputRecordName ( ) const
inlineoverridevirtual
Returns
Input record name of the receiver.

Implements oofem::FEMComponent.

Definition at line 81 of file cohint.h.

References _IFT_CohesiveInterfaceMaterial_Name.

◆ hasAnalyticalTangentStiffness()

bool oofem::CohesiveInterfaceMaterial::hasAnalyticalTangentStiffness ( ) const
inlineoverridevirtual

Tells if the model has implemented analytical tangent stiffness. If not, the tangent must be computed numerically.

Implements oofem::StructuralInterfaceMaterial.

Definition at line 78 of file cohint.h.

◆ initializeFrom()

void oofem::CohesiveInterfaceMaterial::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.

Member Data Documentation

◆ kn

double oofem::CohesiveInterfaceMaterial::kn = 0.
protected

Elastic properties (normal and shear moduli).

Definition at line 60 of file cohint.h.

◆ ks

double oofem::CohesiveInterfaceMaterial::ks = 0.
protected

◆ smoothMag

double oofem::CohesiveInterfaceMaterial::smoothMag = 0.
protected

Smoothing region between tension and compression stiffness. Uses atan(smoothMag*x) function, where (smoothMag*x) needs to be 6 to be 10% off the asymptotic value. SmoothMag is by default 1.e+4. Higher values mean sharper transition.

◆ stiffCoeffKn

double oofem::CohesiveInterfaceMaterial::stiffCoeffKn = 0.
protected

Reduction of normal stiffness when in tension.

◆ transitionOpening

double oofem::CohesiveInterfaceMaterial::transitionOpening = 0.
protected

Opening when material stiffness changes from kn to kn*stiffCoeffKn.
