It is the most fundamental part of material science and it's important you understand some of these ideas going forward.

Dude you know what I think you are probably some ware in at least the top 50 of scientifically acurate channels. keep up the good work.

What if you even believed the Indian fear as actors that tried write about owning it too YouTube Viddy cycle runs using camera and computer trying too claim known n one me made this thing your watching as lives on the moon because picked green non swore hut seven Laplace algerbras catch fish hook non tabled L e meant objected subjected French obvious.

god i fucking love your accent

You haven't even posted anything on the second channel, why should we subscribe

Incredibly well explained! I'm an engineering student and I'm sure that that there is no need to be doing such studies to understand what you explained, well done!

I was learning a lot by this video. I just found a bit uncomfortable because the narrator talks very fast (Though I am not a native english speaker, this may be the reason).

Very good video.
You could have explained the difference between true stress and engineering stress.
It probably goes into too much detail in this video with the purpose of giving an overall overview.
Here is a picture of the difference between true stress and engineering stress.

You came close to defining an additional property-- RESILIANCE. Resiliance is analogous to Toughness, in that it is quantified by the area underneath the stress-strain curve. But the area is measured from strain=0 to the Yield Strain (which occurs at the Yield Stress.) whereas Toughness measures area all the way to the Ultimate Tensile Strain (breaking point.)
The physical characteristic of Resisiance is that it quantifies the amount of energy a material can absorb and still return to its undeformed shape. For a plate, for example, this would be dent resistance. In general, it's a measure of springiness. This differs from Toughness in that Toughness quantifies the energy absorbed (converted to heat and deformation) to rip the material in two. -
I feel like I'm back in my polytechnic again
-
Reminds me of the good old mechanics lectures.. <3 So much nostalgia right now
-
I really enjoy your videos. Pitched at the right level, lots of concepts, explained simply by breaking them down logically. superb work.
-
Thanks for the fantastic resources!
-
lmao about the joke "safety factors differ between industries" with the bent iPhone.
-
From where did you get your degree?
-
But would jet fuel melt steel beams?
-
holy piss im gonna fail my engineering degree
-
So hardness is to compression as stiffness is to expansion?
-
I'm graduating with a degree in Civil Engineering in May and this is the best explanation of basic material properties of seen. Well done.
-
Please, make a video on Fe-C. My pre-engineering teacher at high school explains it so badly. And for this one... Is there any difference between Rockwell an Vickers hardness tests?
