Detailed Description

1D Beam (spring that also bends) finite element in 2D space.

The Displacements at each node are modeled with two translational, and one rotational, degree of freedom.

VectorType pt,
Float w,
unsigned int  order = 0 
) const [virtual]

virtual Material::ConstPointer itk::fem::Element2DC1Beam::GetMaterial ( void  ) const [inline, virtual]

Get/Set the material properties for the element

Reimplemented from itk::fem::Element.

Definition at line 132 of file itkFEMElement2DC1Beam.h.

References m_mat.

virtual void itk::fem::Element2DC1Beam::GetMaterialMatrix ( MatrixType ) const [inline, virtual]

Get the Material matrix

Implements itk::fem::Element.

Definition at line 87 of file itkFEMElement2DC1Beam.h.

virtual const char* itk::fem::Element2DC1Beam::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::fem::ElementStd< 2, 2 >.

virtual unsigned int itk::fem::Element2DC1Beam::GetNumberOfDegreesOfFreedomPerNode ( void  ) const [inline, virtual]

Get the degrees of freedom for each node

Implements itk::fem::Element.

virtual unsigned int itk::fem::Element2DC1Beam::GetNumberOfIntegrationPoints ( unsigned int  order) const [virtual]

Returns total number of integration points, for given order of Gauss-Legendre numerical integration rule.

Note:
This function must be implemented in derived element classes, and is expected to provide valid number of integration points for up to gaussMaxOrder-th order of integration.

virtual void itk::fem::Element2DC1Beam::GetStiffnessMatrix ( MatrixType Ke) const [virtual]

Get the Stiffness matrix

Reimplemented from itk::fem::Element.

Indent  indent 
) const [protected, virtual]

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::fem::ElementStd< 2, 2 >.

virtual void itk::fem::Element2DC1Beam::SetMaterial ( Material::ConstPointer  ) [inline, virtual]

Set the pointer to the Material object used by the element. All derived classes, which use objects of Material class should override this method to provide access to the material from the base class.
