Somebody please help,
In this paper, in question number 4, it gives a stress-strain curve (BTW flipped axis to trick you when finding Young's Modulus) then says:
"State whether the material of the rod is ductile, brittle or polymeric."

Now I know it's brittle cuz it breaks/snaps at a point, and I know that for a ductile material it would curve to undergo plastic deformation, but I'm curious as to what the graph of the polymeric material would look like.

If possible, can someone post an image of the stress-strain curves of ductile, brittle, and polymeric materials being shown side by side?

Thanks.
