Stress not directly proportionate to Strain? Linear static stress analysis

Hi!

I would like to ask about the relationships between strain, stress and displacement.

I have 4 models: Original, Triangle, Circle & Spiderweb.

I did a linear static stress analysis.

 

 

What I am confused about, is why the max von mises stress results don't really tally with that of strain?

In the strain graph, the black line indicates that the green, red and blue lines overlap.

 

Shouldn't the stress graph match up with the strain graph?

 

Your help is much appreciated!:)

Thank you..
