Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

Gotcha. Thanks! Do the points P, E, Y, U, and F stand for something or are the letters arbitrary?

Plastic deformation point, elastic deformation point, yield point, ultimate strength, and failure point

And here I was thinking it was: F U, yep.

E is where it stops being linear, Y is yield, U is ultimate as in max, and f is fracture / failure. Not sure about p.

P is the Proportional Limit, where it stops being linear, but remains elastic for a short while longer, meaning any deformation can still be recovered. E is the Elastic Limit, where it changes from elastic to plastic

Proportional limit. Deformation is linear up until this point.
