Understanding Material Strength, Ductility and Toughness

[@whatistomwithoutjerry6985]

I JUST STARTED MY COURSE IN MECHANICAL ENGINEERING AND NOW THIS GREAT CHANNEL CAME OUT OF NO WHERE PLEASE PLEASE PLEASE KEEP DOING WHAT YOURE DOING

[@UNIQCREATOR]

#iheart_socks subs. My channel for variius such kind of topics.

Are you still in engineering school? Just curious.

[@raxirex6443]

did you finish your bachelors

Funny how KZbin taught me more than School

[@dj_b1627]

Even as an engineer I have to say that your videos are very good. Obviously at university you will get a very detailed view of these topics but you summarize them very well.

[@harmonyOfEureka]

I gave you a thumbs up but I have to say it is still depends on what university. I studied at 1 of the top universities in Japan, but the class doesn't have 3d visual explanation and go in depth as much as this.

[@WhiteDevil47]

@@harmonyOfEurekaI agree with you, I am also in one of the prestigious institute of my country but at the end of the day I have to study most of the topic from KZbin or online courses of MIT,IITetc

[@mavenweak]

finally, there's someone who can explain it more than our university professors

[@aryanvardhan809]

@REPUBBLICA ITALIANA No, the key difference is that visualization is great tool for learning such concepts that most professors don't use effectively.

[@mediwise2474]

Sir I want to learn statics and mechanics what kind of maths is required

I am so hyped, that someone as skilled as you is finally tackling engineering courses. Your channel will escalate (hopefully very soon) if you can keep this up :)

[@GenaEnSamIAm]

Agreed! @The Efficient Engineer , Structural engineering fan in lock down here. I enjoy your content so much. Thank you :-)

[@_Wai_Wai_]

Soon, brick and mortar schools will go away. As they are inefficient and ineffective. Not to mention expensive.

[@ahmedelfathih6322]

As a visual learner I find this channel very helpful. We really appreciate what you are doing. As these concepts are hard to understand but you made look so easy.

[@Freshboyarly]

This channel has never disappointed us. The work here is magnificent.

Great video! As somebody with a fluid/thermal focus during my masters, this is really helping me brush up on solid mechanics knowledge, and far better than it was ever taught to me.

[@babajungLA]

Wow! I spent a whole semester in College learning about materials...I had a tough time grasping basic concepts for some reason...Wish I had videos like this to illustrate how easy the fundamentals are to understand! Amazing Work.

[@moseskieti618]

It has been so helpful to use internet for studying as I per take my diploma in Civil Engineered in Thika Technical Training Institute

[@muhammadmoinirfan3901]

This channel should have at least a million subscribers...

[@clinthightowerclinthightow4950]

The silly music with a topic like this is distracting at best. Take if for what it's worth from a loyal watcher.

[@karrouchekarrouche1151]

I lovee it though😂😂

[@zeynepesrai]

In this way, you showed us that we should not afraid to understand complex and abstract things. Thank you!

No one thought me this in University. All they knew and though us was Ductility is able to draw wire. Please keep doing such videos.

[@jesseycordero7680]

Finally someone has created excellent engineering videos. I am studying for the PE in CA and have had a difficult time finding quality youtube videos explaining some basic concepts. This channel is fantastic! Keep up the work.

[@TheEfficientEngineer]

Thank you!

[@olynikac]

Current mechanical engineering student here. These videos are immaculate. Well done!

[@vnkamath97]

a big thanks for explaining the concepts with animation. Keep making engineering videos which will help us for sure and im sure that u will get subscribers soon :)

[@thoughtful_rider_8559]

Didn't concentrate during this lecture at university, thanks to this amazing video, every concept has been cleared.

[@abubakrkashani1710]

Just incredible! Oh my God. You are amazing! Brilliant brilliant brilliant! Please never stop what you are doing.

[@edikanikpatt8580]

I thank God for the grace of KZbin

Soooo Greattttt.... Watching this makes me realize how inefficient most teachers at colleges really are.... (no offence)

[@UNIQCREATOR]

Subs. My channel for various such kind of topics

[@_Wai_Wai_]

Soon, brick and mortar schools will go away. As they are inefficient and ineffective. Not to mention expensive. I feel like many professors just parrot the previous explanation that was made to them, without realizing that many of the concepts need a slight adjustment in the explanation.

[@kewGarden]

@潘峰威 Funny how people who say that tend to be the bad students.

[@beshkodiak]

A couple of years ago, in a musty little shop i found a book on mathematics for engineers. I was so delighted to thumb through and see the formulas that i had applied in my career. Your channel gives me that same delight. Subscribed!

[@TheEfficientEngineer]

Really glad to hear it, thank you!

[@aryanvardhan809]

Which branch of engineering did you practice?

[@mamba0011]

Can you tell the name of book

[@burhanurrehman2918]

correction at @04:06 "fracture at strain at less than 5 percent" instead of "strain at fracture of less than 5 percent" Thanks for your hard work in making these videos

[@nimadabiri]

Easy to follow description along with a beautiful visual presentation. Great Job! You have a thumb up.

[@GeniusEngineering]

Great overview of these important material properties. Simple and understandable animations along with a great verbal description.

[@henrybristow1928]

All of these videos are really helping me with my IB Extended Essay, thank you so much!

Kill the background music please

[@norbertnagy5514]

Sir

[@MohOEM]

Actually, I think the music is relaxing but it needs to get toned down or replaced with a calmer one like the one he used in other videos..

I wish you had made these videos while I was studying engineering

[@media1critter]

wow, I just love how thorough your explanations are!! Keep it up!!

[@TheGamingGod1989]

I wish I was taught these things in this much easier to understand manner back during my bachelor's degree in materials technology. After a master's in the field, I am now doing my doctorate and need to refresh my memory on the basics since I have forgotten so much of the underlying explanations of the used terminology.

[@rahmanrahmani2896]

Why does someone have to make my dreams come true by making not only physics videos but about engineering.

[@pakassassin9605]

Best video on this topic hand down. Explained thoroughly and concisely.

[@eriktempelman2097]

Improvement: Yield strength is defined as the stress that results in 0.2% permanent deformation (in metals) or as the stress at 1% strain (in plastics).

[@fbdjwjflac]

Yup. He didn’t really go into enough detail on the nuances between the proportionality limit, elastic limit and yield strength.

[@alexhauptman2239]

Great animations, they really help with the concepts and are fun to watch

[@ronmoore6598]

Excellent overview! I didn't remember learning about resilience in school so learned something new there. A small discussion on Bulk Modulus would have fit in well here. It almost seems we could use videos like this instead of classroom teaching. Time to get with the new millenium.

[@ziranduan]

A video about crack initiation, crack damage and volumetric strain would be awesome!

[@dr20231may]

your videos are really good easy to understand and helped me understand mechanics, i suggest ,to avoid sound effects when not necessasy ,for example at 0:15 when you say strenght ... then the keyboard key presses are a bit distracting to me ,thanks

Great video! The only thing I would do. THE ONLY THING is drop the music. It's too reminiscent of instagram pizza popsicle recipe videos.

[@TheEfficientEngineer]

It definitely seems like not everyone likes the music! I will try something different for the next video. :)

[@Jp-ju9nq]

That's strangely specific but far to accurate.

[@cookiemaria780]

Something that has been confusing me for a long while, is the relationship between ductility and toughness. As far as I understand, ductility is a measure of the ability to plastically deform. I also understand that the plastic deformation is the main way that energy is absorbed by the material before fracture. This leads me to believe that materials with high ductility must have high toughness and vice versa, since toughness is the ability to absorb energy before fracture. However, i have seen some things online claiming that high ductility and high toughness do not always go together, and that even some ceramics are tough even though they are not ductile. Can someone please explain this to me? Like how can some ceramics be tough but then not plastically deform? How is the energy being absorbed in this “tough” ceramic? Are toughness and ductility not directly proportional? I need this info for university, would be really grateful for help. Incase anyone reading this is a German speaker, I have a further confusion, that I would love help with. As far as I understand, the translation for the German word ‘zähe’ is ‘tough’ and the translation for ‘duktil’ is ‘ductile’. In german ‘zähe’ seems to be used interchangeably for ‘duktil’, which in english would mean that toughness = ductility. But I can’t believe this is true. We can clearly see that ductility and toughness have different quantitative values. Are the terms used liberally in German? Was ist der Unterschied zwischen zähe und duktil? Bedeuten sie das gleiche auf deutsch? Was ist dann toughness auf Deutsch? Hilfe!

I wish I can watch this video a year ago ... that so helpful ... thanks alot

@The Efficient Engineer would you be interested in doing a video elaborating more on cracking and fracture?
