I hope someone recreates theses pictures with CC license and posts them to the respective Wikipedia entries

The Elasticity (physics) entry doesn't have a single image.

But the sister entry has so many. Obviously not the same authors at all.

Plasticity (physics)
Non-reversible deformation of a solid material in response to applied forces

The elastic band would probably need more conformations to illustrate that only the slack deformation is plastic.

Thanks, I hate it!

Wow, amazing!

I'm much more familiar with those terms being used in the active present tense sense than in a past tense sense. The elastic interval on the strain axis tends to be surprisingly short and plastic deformation can be difficult to detect with the naked eye.

Holding that rubber band and having it stretch due to gravity is almost certainly an elastic deformation. I would be very surprised if there was no plastic deformation from that disposable spoon bending.

A good rule of thumb is: if I cycled this change a bajillion times, would I eventually detect a difference? If you answer yes, then plastic deformation is occurring.

Pretty sure these are reversed

That finger looks shockingly like a penis because of the shadow. I can’t not see it.

You should go get some penis. Sounds like you could really use it.
