Detailed Description

4-noded finite element class in 2D space.

The ordering of the nodes is counter clockwise. That is the nodes should be defined in the following order:

3 (0,1) 2 (1,1) *---------------------—* | | | | | | | | | | | | *---------------------—* 0 (0,0) 1 (0,1)

The constitutive equation used is from the principles of linear elasticity. This class combines the geometry of the FE problem defined in Element2DC0LinearQuadrilateral and the physics of the problem defined in Element2DStress

Member Function Documentation

virtual::itk::LightObject::Pointer itk::fem::Element2DC0LinearQuadrilateralStress::CreateAnother ( void  ) const
virtual

CreateAnother method will clone the existing instance of this type, including its internal member variables.

Reimplemented from itk::LightObject.

virtual const char* itk::fem::Element2DC0LinearQuadrilateralStress::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods).

Reimplemented from itk::fem::Element2DStress< Element2DC0LinearQuadrilateral >.

static Pointer itk::fem::Element2DC0LinearQuadrilateralStress::New ( )
static

Method for creation through the object factory.

virtual void itk::fem::Element2DC0LinearQuadrilateralStress::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
protectedvirtual

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::Element2DStress< Element2DC0LinearQuadrilateral >.
