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
