Member Function Documentation

commitState()

int XC::UpdatedLagrangianBeam2D::commitState ( void  )

virtual

Commit the current element state.

The element is to commit its current state. To return 0 if sucessfull, a negative number if not.

Reimplemented from XC::Element.

Reimplemented in XC::InelasticYS2DGNL, XC::Inelastic2DYS02, and XC::Inelastic2DYS03.

getMass()

const XC::Matrix & XC::UpdatedLagrangianBeam2D::getMass ( void  ) const

virtual

Returns the mass matrix.

Returns the mass matrix. The element is to compute its mass matrix based on the original location of the nodes and the current trial response quantities at the nodes.

\[ //! M_e= {\frac{\partial I_i}{\partial \ddot U} \vert}_{U_{trial}} //! \]

Reimplemented from XC::Element.

getNumDOF()

int XC::UpdatedLagrangianBeam2D::getNumDOF ( void  ) const

virtual

return the number of DOF associated with the element.

To return the number of dof associated with the element. This should equal the sum of the dofs at each of the external nodes. To ensure this, each subclass can overwrite the DomainComponent classes {setDomain()} method.

Implements XC::Element.

getResistingForce()

const XC::Vector & XC::UpdatedLagrangianBeam2D::getResistingForce ( void  ) const

virtual

Returns the resisting force vector for the element.

This is equal to the applied load due to element loads minus the loads at the nodes due to internal stresses in the element due to the current trial displacement, i.e.

\[ R_e= P_{e} - {R_e}(U_{trial}) \]

Implements XC::Element.

Reimplemented in XC::InelasticYS2DGNL.

getResistingForceIncInertia()

const XC::Vector & XC::UpdatedLagrangianBeam2D::getResistingForceIncInertia ( void  ) const

virtual

Returns the resisting force vector including inertia forces.

Returns the action of the element over its attached nodes.

Returns the resisting force vector for the element with inertia forces included. This is equal to the applied load due to element loads (loads set using addLoad(), minus the loads at the nodes due to internal stresses in the element due to the current trial response quantities, i.e.

\[ R_e = P_e - I_e (\ddot U_{trial}) - R_e(\dot U_{trial}, U_{trial}) \]

Computes damping matrix.

Reimplemented from XC::Element.

getResponse()

int XC::UpdatedLagrangianBeam2D::getResponse ( int  responseID, Information &  eleInfo  )

virtual

Obtain information from an analysis.

getResponse is a method invoked to obtain information from an analysis. The method is invoked with the integer argument returned and the Information object that was prepared in a successfull {setResponse()} method invocation. To return \(0\) if successfull, a negative number if not. The base class implementation will always return \(-1\).

Reimplemented from XC::Element.

Reimplemented in XC::InelasticYS2DGNL.

getTangentStiff()

const XC::Matrix & XC::UpdatedLagrangianBeam2D::getTangentStiff ( void  ) const

virtual

Return the tangent stiffness matrix.

To return the tangent stiffness matrix. The element is to compute its stiffness matrix based on the original location of the nodes and the current trial displacement at the nodes.

\[ K_e = {\frac{\partial f_{R_i}}{\partial U} \vert}_{U_{trial}} \]

Implements XC::Element.

Reimplemented in XC::InelasticYS2DGNL.

revertToLastCommit()

int XC::UpdatedLagrangianBeam2D::revertToLastCommit ( void  )

virtual

Revert to the last commited state.

The element is to set it's current state to the last committed state. To return 0 if sucessfull, a negative number if not.

Implements XC::Element.

setResponse()

XC::Response * XC::UpdatedLagrangianBeam2D::setResponse ( const std::vector< std::string > &  argv, Information &  eleInfo  )

virtual

setResponse() is a method invoked to determine if the element will respond to a request for a certain of information.

The information requested of the element is passed in the array of char pointers argv of length {em argc}. If the element does not respond to the request a \(-1\) is returned. If it does respond, an integer value greater than or equal to \(0\) is returned. This is the responseID passed in the getResponse() method. In addition the Element object is responsible for setting the Information object eleInformation with the type of the return, i.e. {IntType, DoubleType, MatrixType, VectorType, IDType}, and for creating a Matrix, Vector or ID object for the Information object, if the information to be returned is of any of these types. The information object is responsible for invoking the destructor on these objects. The base class responds to no requests and will always return \(-1\).

Reimplemented from XC::Element.

Reimplemented in XC::InelasticYS2DGNL.

update()

int XC::UpdatedLagrangianBeam2D::update ( void  )

virtual

Updates the element state.

This method is invoked after the response quantities have been updated in the Domain, but not necessarily committed, e.g. during a non-linear Newton-Raphson solution algorithm. To return \(0\) if successful, a negative number if not. This base class implementation returns 0.

Reimplemented from XC::Element.

Reimplemented in XC::Inelastic2DYS02.
