Detailed Description

3-noded finite element class in 2D space for linear elasticity problem.

This element is combined from Element2DC0LinearTriangular and Element2DStrain.

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

(0,1) 2

• |\ | \ | \ | \ | \ | \ *---—* 0 1 (0,0) (0,1)

This class combines the geometry of the FE problem defined in Element2DC0LinearTriangular and the physics of the problem defined in Element2DStrain

Construct an element by specifying pointers to 3 points and a material.

Member Function Documentation

virtual::itk::LightObject::Pointer itk::fem::Element2DC0LinearTriangularStrain::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::Element2DC0LinearTriangularStrain::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

static

Method for creation through the object factory.

virtual void itk::fem::Element2DC0LinearTriangularStrain::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::Element2DStrain< Element2DC0LinearTriangular >.
