Understanding True Stress and True Strain

[@MegaOjetemoreno]

As a former engineering student and a current engineering professor, I can only applaud these videos. I wish I had this during my student times. I recommend these videos to my students but I think they do not grasp how lucky they are for having this learning material.

[@ericmanternach2340]

You're right, these videos are fantastic. Less Boring Lectures is another channel with excellent videos. This one about bolt pre-tensioning is so good in my opinion: kzbin.info/www/bejne/hKStYaiJbNiNrtE

[@mattderickson3426]

I was just thinking this exact same thing. I wish I had these videos 5 years ago for the conceptualization of these topics! Great job with the videos!

[@eboian_x6522]

True sir as a student I must say KZbin is givin us much luck

[@rodrigof.3488]

Sí, ahora toca aprender también inglés🤠

[@sebakoli6781]

Question: We can not use engineering and true stress relation after necking but what about strain? Can we use this strain relation abeyond necking?

[@ScarletKnightmare]

The quality and clarity of your videos are second to none. Thanks, from a non engineer.

[@mansaranbaath3534]

As a mechanical engineering student in my third year I must applaud you for explaining these crucial concepts with such simplicity. The mark of an excellent teacher.

[@i8764theKevassitant]

How long are you going to school and what degree do you get?

[@moaqirahmad5948]

Just revised my engineering... keep it up... you are a good teacher...

[@justinroy5298]

I'm a engineering student, yours videos are the best. please, never stop doing what you are doing.

[@neelgkumar]

Great video. One another possible reason why engineering stress is used in practice, in addition to difficulty in measuring true stress, is that it better reflects real-life loading scenarios in the sense that the applied load doesn't change when necking initiates.

[@wyllerdesousa1955]

I'm from Brazil and I learn a lot watching your videos. I'm engineering student and I have no patience for waiting the class for learn. Because of people like you we can learn everywhere. Thanks a lot.

[@sulskull]

I cannot thank you enough! As a student of mechanical engineering, your videos are unbelievably useful!

[@eliejororirakiza2202]

Never understood one thing about this in college, understood all of it in a 6 min video

[@daviddemiguel1614]

Hi! I’m a Materials Engineer and I know that these concepts are sometimes difficult to understand. So, I appreciate your video because you achieve to explain it clearly. Nice job mate!

[@Danielagostinho21]

Ok! that's it! The other day I let you go free without this. but today, you wont escape for this: I'm subscribing to your channel even If you don't want to. In a serious note: Amazing channel you got there! Keep up the good work!

[@TheEfficientEngineer]

Thanks a lot Daniel! :)

[@mohabsoliman7172]

animations make life easier . this channel is awesome . thank you so much

[@chiragdugar8183]

Your way of explaining things is great!! You're one of the best. Please don't stop making such videos, I can see this channel growing exponentially in the near future.

[@nowyouknow-sortof]

Thank you!! I had only studied Engineering stress-strain curves and it had been bugging me as to how they ended up at such a curve from the results of a UTS test, whether the reduction in cross-sectional area was taken into account or not. You answered it on point! Thank you so much.

[@math4engzz664]

Great video as usual! I would just like to add that in structural engineering we don't design structures to remain elastic (at least in reinforced concrete), but we still use engineering stress for design because most of the time we work with uniaxial stresses and strains (for example, we simplify reinforcement bars and we assume they are linear elements instead of 3D elements).

[@mollysmith2713]

Thanks!

[@chinmaygourkhede5380]

Thank you for the dark background , Helps my eyes when I watch ur videos at 2am

[@DrSami315]

I appreciate the amount of efforts you put into your videos! I will recommend your channel to my followers! All respect, Hamid :) from Princeton University.

[@TheEfficientEngineer]

Thanks Hamid! :)

[@mayanklakhera527]

Haven't seen any better channel on youtube. Great work guys.

[@physicslover1950]

This is the way our university teachers should teach us. Your concepts are crystal clear. So I want you to make a video on a topic which is unclear to most of egineers . It is the analysis of flexible cables for both concentrated and distributed loads. You must have good visualiw about it I am sure I can't stop myself from subscribing you . You are awesome

[@pedromanuelcastorena8525]

I love your videos (from a mechanical engineering undergraduate student)! Keep up the good work. [Consider making these type of videos for a typical undergraduate materials science course]

[@jatto9856]

How in the world is your content free on youtube?! Your videos are simply amazing and really helped me a lot, Cheers!

[@nuclearmage]

Where were you when I was in undergrad and grad school?!?! Great videos by they way, I am using it to refresh my engineering math for job interviews.

[@mozammelmia3714]

Awesome. I am a doctoral student, and found your videos amazing. Super easy to understand, but extremely effective. Many thanks.

[@SouvikCivil]

This lecture was indeed the best among all the other lectures i came across on youtube....!! Hats off to u sir and huge respect to your amazing explanations skills!! < & love from JADAVPUR UNIVERSITY.

[@BrayandPerez]

One of the best videos I've seen in a while 👏🏼

[@jhn1016]

[@en6waeii]

Thank you, you're indeed the best engineering tutor on this platform

[@simeonogbonna568]

I can't just get enough of your awesome explanations. I will certainly recommend your channel to my fellow engineers

[@TheEfficientEngineer]

Great to hear, thanks Simeon!

[@muhammadzraittayyab9596]

Better than Indian you tube channels' videos on this topic

[@GasPa-s1o]

As an engineering student, I can say that this video is nothing but brilliant

[@abbosbekkhudayberganov820]

so this is where the engineering memes come from: e = 2.71 ~ 3, π = 3.14 ~ 3 therefore e = π ... if it's close enough, it's good enough😂

[@Albian2405]

This is the best engingeering videoes I have ever seen! Thanks alot for the uploads! Best regards from an civil engineer student

[@pavankumar132]

Concepts are explained very clearly I'm having my FEM subject this semester and you're helping me allot

[@bobo123125]

Thank you very much mate and may God bless you and guide you to the righteous path.

[@shahidchaudhary52]

So to sum up : True stress and strain is mostly higher than engineering stress and strain ( which we calculate theoretically). But with the help of this equations 6:30 true stress and strain can be easily calculated

[@habeebbabatundeajose3537]

I need more of your videos on strength of materials.

[@madhusudhanmsd1321]

Your vedios are gems , it needs to go viral among mechanical engineers, Please make more vedios You are going places!!

The concepts you describe in your videos are simply amazing, easy to understand and engrossing. Please keep up the great work. With Respect Parijat (IIT Kharagpur, India)

[@charles-antoinegagne6109]

Thank you for clarifying that point. That bugged me ever since because it was never clear which area the load was divided by. It just didn't make sense to me that the strenght of the material was getting worse when it's cross sectional area was smaller for a bigger load.

[@LikhitK]

I thank you from the bottom of my heart!

[@BoZhaoengineering]

This is a missing part when I was learning the stress - strain test. True strain and stress are precisely depicting the tensile experiment.

[@hikirj]

This was so useful, thank you so much!

[@greenfoodpower6961]

Excellent Lecture!

You can also define the engineering stress using the curriculum modulus / target time of graduation -formula

[@adiladeeb2899]

hello, i am from India. by looking at your content it looks like you are either from civil or mechanical background. i am studying civil right now . JUST LOVE YOUR VIDEO. DON'T STOP. can you do more civil related videos. i have many doubts from strength of materials, structural analysis and environmental eng subjects. can you do more videos on then .The graphics and explanation is great. Thanks.
