It''s very interesting to see how things work practically instead of just reading it from books.
Exactly
Totally agree.

No idea why this was in my recommendations, but I watched it and it was interesting. Props for Anneke Reinsperger for speaking English without even the hint of a German accent.
Very clear speaking.
I searched it to see with my eyes what I was studying (for an exam about polymers)
This proved to be very helpful in my engineering practical exams .
🙏🏻
I dont work in material science just needed to learn something for work so I landed on your video. Not only the content of the video is informative but I also find how the entire process is explained is very neat! Thank you for sharing!
I'm studying for the metallurgy exam at university and this video helps a lot to visualize and really understand how the complete process works.
Grande bro
Never quite understood why we always had two different graphs but thanks to this video it's very clear. Great stuff
Finally some really good videos on materials testing. Thanks!!
this is the best video on tensile testing and strain on CZcams
The best video I ever saw on this, keep it up! thank you for showing the curve as the test proceeds..
thank you so much for this video, while my professor has excellent knowledge we learn little so these videos are a lifesaver.
This video is really well made, thank you for making it. Finally some really good videos on materials testing. Thanks!!.
This is an insteresting and informative video. I'm a Mechanical Engineering and this information clarifies some concepts.
Best Tensile Test video in internet.
Congratulations for your work, this is very helpful for beginners/students and experts. :)
This video is really well made, thank you for making it
Very informative without any fuzz!
I’m in 6th grade and this was the first advanced thing I’ve learned like this so thx
Very informative and very proffesional. Thank you
Thanks for your video, it was helped me to finish my final project
Now thats what u call, THE BEST..!!
Very neat! We just went over these concepts in Solid Mechanics.
thank you so much ,your voice is great ; peace from morocco
amazing vid, love it! thanks!
Thank you. It really helps me a lot for preparing my exam
This video is very informative and has good explanation. Thank you
nice video.this video is much more suitable for professionals than students. this is widely used in industries. well we had this experiment done during my engg time.
wow!! thx guys. now i got the practical knowledge from your video.
This video is very helpful.
Thank You.
Thankyou for uploading this. It was really helpful 🙏
What happy as same the company in your industry, I am a China company, good video!
very important test, thanks guys!
This was highly informative, thank you.

Thank you for posting, it was useful.
Mechanical stress sigma is always defined as Force F divided by cross sectional area S (or area A). Or more precise: NOMINAL stress sigma equals force F divided by ORIGINAL cross sectional area S zero.
In the video TWO physical quantities are plotted on the vertical axis: Force F on the right side and stress sigma on the left side. Sorry for this, it may be confusing. You get sigma on the left side by simply taking F and dividing it by the original cross sectional area S zero.
Great video, Thank you.
Amazing video helped me a lot with my project.
Very helpful, Thanks!
This essay is great because it exemplifies that not all materials work in the same way.
Thanks alot ! Perfecttt!
Excellent! Thank you !!

Thank you very much for your help
In materials of medium or low ductility, the fracture may take place anywhere along the prismatic part of the specimen, mostly at a weak point. In very ductile materials, the fracture tends to form in the middle region, because there is a certain influence of the grip regions.
my mind just exploded. This is gonna be a fun semester

I'm not even sure how i ended up here but this is fascinating
AMAZING EXPLANATION
It is a good video, it explains the procedure very well.
It’s a very helpful video. Thanks alot
Great video!
Good presentation as well as explanation.
Amazing experience.
Explained in a simple way
It is interesting to see how steel can deform under load applications in a test. Thank you for made it
Very good. The video is brilliant
Too much helpfull practical knowledge
Thank you so much for this video and for your explanation
It is really interesting. Good presentation.
Very much informative thanks a lot !!!
This is very well done, it helped my studies.

More information about yield phenomenon, please. That was very interesting, informative and helpful
Cool machine!
I'm a sample machinist for the local steel mill and this is exactly what I machine every day.
"Why does the machine not apply any additional force in the 'luda' (Lüder) area of the curve?": This is an important question, and a research topic of mine, please see our publ. "On the nature of the yield point phenomenon" in Acta Materialia. "And why does the machine apply less and less force right before final fracture?" This is due to "material instability": Here the strain hardening effect is not strong enough to compensate the strength decrease due to the decrease in cross sectional area.
what can you conclude about the yield strength of the two specimen tested here?
Thank you very very much.
Excellent explanation
The term "elongation" in ASTM 615 indeed is not specified clearly. To my knowledge it can only mean "percentage elongation after fracture". So one has to put the fragments together and then determine the percentage plastic deformation after fracture has occurred.
This is extremely fascinating. I'm super motivated to finish my remaining education. Working two full time jobs for school has been very tiresome.
well done *claps*

It is very useful to know the material
Answer to "It is very useful to know the material": Quite correct, the steel is a typical plain low-carbon structural steel, type S235JR. The aluminium alloy is a 2014 precipitation hardened alloy with about 4 % Cu and some small additions of Si and Mg.
"what would be if we take off tension on the middle of experiment for example on 18mm elongation. and apply it again?" Then an elastic spring-back parallel to the elastic straight line would take place, not to the original length, but to the plastically strained length of about 17.8 mm. On reloading, after elastic behaviour the original curve will be resumed, as if nothing had happened.
Cool. I like videos like this.
"If this rod was a hollow tube or pipe how would the inner diameter be effected? Am I to assume that the point at which it would neck the inner diameter would increase roughly as much as the outer diameter decreases?" We do not have much experience on tensile tests of tubes, but as far as I know, the inner diameter at the neck will decrease, and the outer diameter as well, a bit more than the inner one. So from the side, the broken tube looks similar to the massive cylindrical specimen.
Thank you for this
Thank you.
Nice! Very helpful.
(Explain the concepts used in the tensile test on the tensile diagram of st 37 steel)
Can someone help me with this question please?
Very well explained
thank you..very much
Great Video :)

Thank you.
very helpful
I thank you
Thank you for your interest. We are sorry to state, that there is no Spanish text available, and we would not like to hand out the English or German text.
It would be valuable to add to the charpy energy testing video to include %shear area determination and may be include a drop weight testing video with %shear area determination.
I like this video.
it is very much useful
This is so cool, do you have a video with temperature instead of force aswell?
