Detailed Description

template<class TBaseClass = Element>
class itk::fem::Element1DStress< TBaseClass >

Class that is used to define linear elasticity problem in 1D space.

This class only defines the physics of the problem. Use his class together with element classes that specify the geometry to fully define the element.

You can specify one template parameter:

TBaseClass - Class from which Element1DStress is derived. TBaseClass must be derived from the Element base class. This enables you to use this class at any level of element definition. If not specified, it defaults to the Element base class.

Member Function Documentation

template<class TBaseClass = Element> virtual Material::ConstPointer itk::fem::Element1DStress< TBaseClass >::GetMaterial (  void   )  const [inline, virtual]

Definition at line 113 of file itkFEMElement1DStress.h.

template<class TBaseClass = Element> virtual void itk::fem::Element1DStress< TBaseClass >::GetMaterialMatrix (  MatrixType &  D  )  const [virtual]

Compute the D matrix.

template<class TBaseClass = Element> virtual unsigned int itk::fem::Element1DStress< TBaseClass >::GetNumberOfDegreesOfFreedomPerNode (  void   )  const [inline, virtual]

1D stress elements have 2 DOFs per node. In reality there is only one, but it usually makes sense to separate it into the components that correspond to specific dimensions in space. So the number of DOFs per node is equal to the number of spatial dimensions. Definition at line 102 of file itkFEMElement1DStress.h.

template<class TBaseClass = Element> virtual void itk::fem::Element1DStress< TBaseClass >::GetStiffnessMatrix (  MatrixType &  Ke  )  const [virtual]

Element stiffness matrix is reimplemented here, because we want to be able to use this class to implement 1D stress problem in any number of dimensions i.e. Bar1D, Bar2D, Bar3D.

template<class TBaseClass = Element> virtual void itk::fem::Element1DStress< TBaseClass >::GetStrainDisplacementMatrix (  MatrixType &  B, const MatrixType &  shapeDgl )  const [virtual]

Compute the B matrix.

template<class TBaseClass = Element> virtual void itk::fem::Element1DStress< TBaseClass >::Read (  std::istream &  , void *  info )  [virtual]

Read data for this class from input stream

template<class TBaseClass = Element> virtual void itk::fem::Element1DStress< TBaseClass >::SetMaterial (  Material::ConstPointer  mat_  )  [inline, virtual]

Definition at line 114 of file itkFEMElement1DStress.h.

template<class TBaseClass = Element> virtual void itk::fem::Element1DStress< TBaseClass >::Write (  std::ostream &  f  )  const [virtual]

Write this class to output stream
