Manager "So all that you need is more strain to reduce the stress? Here are 10 more tasks which should strain you quite a bit"

Have considered recrystallisation ~~therapy~~

Well, mom, maybe write like a 60-year-old and not a 14-year-old and I'll respond.

[-] captainlezbian@lemmy.world 3 points 6 days ago

Ouch yes, very true, but ouch

[-] Kyrrrr@lemmynsfw.com 56 points 1 week ago

Ah yes the part of the curve where the stress permanently changes you. Yeah, accurate.

[-] elbowgrease@lemm.ee 38 points 1 week ago

this assumes a ductile material. I myself am smiling as though everything is fine in the elastic region and may snap at any moment.

What a fragile personality...

[-] elbowgrease@lemm.ee 8 points 6 days ago

brittle. brittle materials fail in the elastic portion of the stress strain diagram

Found the titanium personality

Can a TI-84slinger explain this for us pipette-wielders?

[-] HootinNHollerin@lemmy.world 52 points 1 week ago

Past the elastic deformation region / yield stress you get plastic deformation, which even when the stress is completely removed there is permanent deformation.

[-] Someonelol@lemmy.dbzer0.com 4 points 6 days ago

Looks like the plastic deformation point was placed before the elastic point.

[-] Rubisco@slrpnk.net 16 points 1 week ago

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

[-] Dettweiler42@lemmy.world 36 points 1 week ago

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

[-] Dave@lemmy.nz 6 points 1 week ago

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

[-] HootinNHollerin@lemmy.world 10 points 1 week ago

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.

[-] LeftRedditOnJul1@lemmy.world 21 points 1 week ago

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

[-] andrewth09@lemmy.world 11 points 1 week ago

Proportional limit. Deformation is linear up until this point.

[-] Dettweiler42@lemmy.world 25 points 1 week ago

Everything past the dotted line is the point where the material won't go back to its original shape.
Example: You can push on the hood of your car all you want, it'll flex, and go back to its original shape (elastic deformation); but stand on it, and it'll dent (plastic deformation).

"have you tried modeling this with something more flexible?" -The Project Manager.

[-] Aurenkin@sh.itjust.works 10 points 1 week ago

The plastic zone is no joke, my friend.

[-] FuglyDuck@lemmy.world 1 points 6 days ago

Is it sort of like the friend zone?

[-] Aurenkin@sh.itjust.works 2 points 6 days ago

Indeed, it leaves you forever deformed.

[-] fckreddit@lemmy.ml 6 points 1 week ago

The material is too ductile. I am at the peak of a narrow yield curve and then, snap, material breaks.

[-] NakariLexfortaine@lemm.ee 8 points 1 week ago

Well, do we have some good news for you about what's currently in your body...

Yeah when I jerk off I cum credit cards.
