Difference between Yield Strength and Ultimate Strength

This video explains the difference between Yield strength and Ultimate strength. Yield strength can be defined as the strength of the material where the material starts to yielding. Yielding is the point where the molecules of the material reshape and take starting further load. Whereas ultimate is the maximum strength value that material can take.

yield strength or elastic limit, the point where the stress induced causes no permanent deformation of material.

Well illustrated!

Thank you

[@mohamadkhatib8624]

So sir when we do analysis loads we should only consider elastic limit right ? Which is yield strength point ?

[@SeventhSigmaMale]

What if material stress value at ultimate strength is same as yield strength point, does that mean 0 Factor of Safety?

[@virenjayasinghe3070]

BOth MAx load and Upper Yield strength is same ?

[@drewnix7201]

thank you sir

[@冯孝伟]

should the specimen has to be a defined shape ?

[@NAKK786]

Is there any relationship between ys and uts??
