Applying plane stress boundary conditions to a single element

[svishal03]

Dear All,
I just have a single element, I need to apply a plane stress condition as in the attached image.

For the boundary conditions;
• I have constrained the nodes 1 and 2 in the horizontal (x) direction
• I have constrained the nodes 1 and 3 in the vertical (Y) direction
• I have constrained nodes 1,2,3 in z (perpendicular) direction.
• I have got a constant stress and strain throughout the element

Are the results i.e. stress distribution correct qualitatively? Have I applied the boundary conditions correctly?

Please can anyone advise?
