Detailed Description

Simple isotropic damage based model for 2d and 3d 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.

In 3d, the interface elements are used to model contact layer between element surfaces. 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 a table given by a file that relates the normal displacement to the damage. A linear interpolation is made between the values given in the table. If the strain is greater than the largest value in the table the largest damage in the table will be used.

Member Function Documentation

◆ computeDamageParam()

double oofem::IntMatIsoDamageTable::computeDamageParam ( double kappa ) const

computes the value of damage parameter omega, based on given value of equivalent strain.

Parameters

kappa	Equivalent strain measure.
strain	Total strain vector in full form. (unnecessary?)
gp	Integration point.

Returns: omega.

◆ initializeFrom()

void oofem::IntMatIsoDamageTable::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
