Detailed Description

Simple isotropic damage based model for 2d interface elements with rate dependence. 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.

Member Function Documentation

◆ checkConsistency()

int oofem::IntMatBilinearCZFagerstromRate::checkConsistency ( void )

overrideprotectedvirtual

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.

Setups the input record string of receiver.

Parameters

input Dynamic input record to be filled by receiver.

◆ hasAnalyticalTangentStiffness()

bool oofem::IntMatBilinearCZFagerstromRate::hasAnalyticalTangentStiffness ( ) const

inlineoverridevirtual

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

◆ initializeFrom()

void oofem::IntMatBilinearCZFagerstromRate::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.
