Detailed Description

This class represents a "simple" interface material which is linear elastic in the normal direction. It is similar to a Coulomb contact model in the sense that the maximum shear stress is bounded by the normal stress times the coefficient of friction.

◆ hasAnalyticalTangentStiffness()

bool oofem::IntMatCoulombContact::hasAnalyticalTangentStiffness ( ) const

inlineoverridevirtual

Definition at line 115 of file intmatcoulombcontact.h.

◆ initializeFrom()

void oofem::IntMatCoulombContact::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
