Do you have theoretical description also for the ductile material reverse loading ? How plastic hardening changes the stress- strain curve in oppsite direction? The alternative question: Is a common ductile steel beahviour simillar to "Isotropic hardening" or "kinematic hardening", or other model ? So far this video seems to me only general talking about nothing, carefully avoiding anything what could be interesting.
ultimate strength is represented by the highest point on the stress/strain curve. it is the max stress the material sees during a tensile test. if you look at the curve for a tensile test, the strain hardening is the portion of the curve that rises up to meet the ultimate strength point. But if you keep stretching the sample past that point, the material starts necking, stress goes down as strain continues, up until the point of failure.
thanks for helping me pass my material science class
Very easy to understand and very straightforward, cheers!
Thank you Sir for making this video. The information was conveyed in a very practical manner.
Clearly explained. Thank you so much!
Thank you..this answered a LOT of questions...
I understood everything when I imagined unloading and loading
It very clear. Thank you
This is very useful, thank you so much sir!
It was very useful, thank you sir
super!!!
perfect
Thank you
Thank You sir for the video
thanks
thank you sir
life saver!!! thank you good sir

But sources say that the ULTIMATE Strength also increases? Why would this be?

thanks a lot
what is the difference between work hardening and strain hardning?
Jansi Babu they same

Whenever, I have bent wires to the point of failure I'm sure it felt like it was easier to apply stress after each bend. Why is this?
I think that, at the area of bend, the grain boundary keeps reducing. Smaller the grain boundary it is easier to break. The malleability too reduces
Because, wire loosing its elastic property every time you bend wire
Thank you
