Detailed Description

6-noded finite element class in 2D space for linear elasticity problem. The constitutive equation used is for plane stress.

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

(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 Element2DStress
