Detailed Description

Base class for cross sections with yield surface on a bi-dimensional space (three DOFs for each section).

Member Function Documentation

getResponseType()

const XC::ResponseId & XC::YieldSurfaceSection2d::getResponseType ( void  ) const

virtual

Return the ordering and type of response quantities returned by this object.

Return the section ResponseId code that indicates the ordering and type of response quantities returned by the section. Lets the calling object (e.g. an Element) know how to interpret the quantites returned by this object.

Implements XC::SectionForceDeformation.

getSectionFlexibility()

const XC::Matrix & XC::YieldSurfaceSection2d::getSectionFlexibility ( void  ) const

virtual

Returns the tangent flexibility matrix of the section.

Obtains the section tangent stiffness matrix, \(ksec\), and returns its inverse, the section flexibility matrix, \(fsec\), via an explicit matrix inversion. NOTE: The explicit matrix inversion provides default behavior and may be overridden in subclasses to suit specific SectionForceDeformation implementations.

Reimplemented from XC::SectionForceDeformation.

getSectionTangent()

const XC::Matrix & XC::YieldSurfaceSection2d::getSectionTangent ( void  ) const

virtual

Return the section tangent stiffness matrix, \(ksec\), at the current trial state.

Implements XC::SectionForceDeformation.

getStressResultant()

const XC::Vector & XC::YieldSurfaceSection2d::getStressResultant ( void  ) const

virtual

Return the section resisting forces, \(ssec\), at the current trial state.

Implements XC::SectionForceDeformation.

recvSelf()

int XC::YieldSurfaceSection2d::recvSelf ( const Communicator &  comm )

virtual

Receive the object.

Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through cp. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using #theBroker. To return 0 if successful or a -1 if not.

Implements XC::MovableObject.

sendSelf()

int XC::YieldSurfaceSection2d::sendSelf ( Communicator &  comm )

virtual

Send the object.

Each object has to send the data needed to be able to reproduce that object in a remote process. The object uses the methods provided by cp object to send the data to another channel at the remote actor, the address of the channel is set before this method is called. An object of similar type at the remote actor is invoked with a receiveSelf() to receive the data. Returns 0 if successful (successful in that the data got to the channel), or a - if no data was sent.

Implements XC::MovableObject.

setTrialSectionDeformation()

int XC::YieldSurfaceSection2d::setTrialSectionDeformation ( const Vector &  )

virtual

Set the value of the trial section deformation vector, \(esec\) to be {def}.

To return \(0\) if successful, a negative number if not.

Implements XC::SectionForceDeformation.
