Detailed Description

6-noded finite element class in 2D space for linear elasticity problem that defines a triangle element.

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

     (0,1)
     2
     *
     |\
     |  \
     |    \

(0,0.5) 5 * * 4 (0.5, 0.5) | \ | \ *--—*--—* 0 3 1 (0,0) (0,0.5) (0,1)

• This class combines the geometry of the FE problem defined in Element2DC0QuadraticTriangular and the physics of the problem defined in Element2DStrain

This element is combined from Element2DC0LinearTriangular and Element2DStrain.
