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.
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.
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 :)
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 :)
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!
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.
@The Efficient Engineer would you be interested in doing a video elaborating more on cracking and fracture? Perhaps a video about the parameters (which i am currently studying and getting a bit confused by!): G - Energy release rate G_1c Linear Elastic Fracture J - Elastoplastic energy release rate J_1c Elastoplastic fracture?
Yes, it's the totality of beautify of a machines where it equate to variable such as efficiency, speed, energy..the total beauty and synchronized of science. Did you see the improve theory of gravity, where I combine the total macro and micro of physical world in to a model to describe events and known phenomenal..
Great Video on the mechanical properties off the stress (psi) vs. strain (inch/inch) dealing with terminology needed for shop-floor fabricators and welders. Thanks for a great job! T J (Tom) Vanderloop, CMfgE; ATEA, AWS, and SME Leadership/Memberships (Author, CAD-Designer & Consultant.)
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!
Dear engineer I rigorously follow your videos and I don't think there is any student who doesn't understand them. Thank you very much for the explanations. Generally, in all the videos where -TAU- the shear stress (of the steel) is needed, the value of this is more or less 0.6 of the normal stress. Like the shear stress I would like to know (in the case of two plates that rotate on a steel link) in order to be able to know THE necessary THICKNESS of the plates that are not produced in them flatteningas, the flattening stress is calculated , of the steel?
I saw you finally define ductility well but showing the range of ductility from beginning to the end on the stress-strain curve which I thought is not correct, it should be from yield strength point to till fracture point.
Awesome content with a clear description !! Can you provide any info about the difference between softening temperature and glass transition temperature?
Softening temperature is the temperature at which material will become relatively soft at higher temperature i.e flat ended needle penetrates to a depth of 1 mm under a specific load while DBT is the temperature below which material behaves as brittle.
Great Work Sir! you should upload as much videos as you can for the promotion of your channel. I'm also promoting your channel by advising my friends to watch your videos.
I see that steel for example has a yield strenght of about 1000MPa (1GPa), so it means it breaks after pressures above that point? Then what does the module of elacticity means when steel has 210 GPa?
I got a doubt. How are the large stress concentrations at crack tip of a brittle materials (in contrast to plastic deformation which reduces localised stresses in ductile materials) a factor for having compressive strength greater than tensile strength in brittle materials?
3:24 if the definition of ductility is the ability to deform plastically then 6:58 shouldn't the ductility on the graph be from yield point to fracture?
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.
@@TheEfficientEngineer Yes, have noticed it when I watched your recent videos. They are much better in that regard. I really appreciate it. But still, personally, I would prefer no music at all. It would make it much easier for me to focus.

It has been so helpful to use internet for studying as I per take my diploma in Civil Engineered in Thika Technical Training Institute
In this way, you showed us that we should not afraid to understand complex and abstract things. Thank you!

Really glad to hear it, thank you!
Which branch of engineering did you practice?
Can you tell the name of book
you did something 5 years ago but its still very usufull , thank you mate for this channel
Kill the background music please
Sir
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..
Why?? Its a banger.
I actually really like it lol
Amen
Current mechanical engineering student here. These videos are immaculate. Well done!
All of these videos are really helping me with my IB Extended Essay, thank you so much!

Please put up more such a videos on civil subjects ...it will be very useful for many of us.
Thank you for your amazing work : )
Lloyd Smith you have the Coolest channel ever !
This channel deserves more views and subscribers
Who is the nonsense who dislike such informative demo of mechanics
You are truly amazing! I learn more in 7mins that I do in 3 months of university
Very good teaching and presentation
Very good video sir really usefull
your videos are awesome. My professor of this subject at university have a bad didact so you are helping me a lot
Amazing UA-cam channel!
I loved thus video..trying to understand these from ages,..your presentation made it easier to understand and remember
Great Video. You are a nice teacher.
a great learning platform indeed-this channel
Wish I had your videos when I was in college!
it will be amazing if there is a pdf to this amazing video to summarize it.
It is good for engineers mechanical properties at room temp and transition temp for steel as well as ductile iron for windmill castings
@The Efficient Engineer would you be interested in doing a video elaborating more on cracking and fracture? Perhaps a video about the parameters (which i am currently studying and getting a bit confused by!):
G - Energy release rate
G_1c Linear Elastic Fracture
J - Elastoplastic energy release rate
J_1c Elastoplastic fracture?
Very good lecture.
Many thanks sir
Thank you, great videos... I hope they will be videos about composite materials, its hard to find
I wish I can watch this video a year ago ... that so helpful ... thanks alot

Congrats! Extremely legible ! You have a new suscriptor
Nice explanation.. can you please elaborate difference between Engineering Stress and True stress. Also explain Von Moises stress.
Thanks! I've already covered both of these topics in separate videos.
This is incredible ... Love u as well as ur channel ... As well as ur efforts ....
nice explanation
Amazing explaination ! would you mind me asking what is the name of the background music?
if only i found this earlier thank you so much
I LOVE YOUR VIDEO BRO!!!.... Thank you for sharing
great
Very clever explained, thank you a lot.
This video is so helpful for me, Thank you so much.
excellent video! Very well explained and things are more clear now to me! Thanks a lot!
Pls make more videos on engineering applications
Good video. Very loud background music. It is a disturbance in technical videos.

Awesome explanation.
very helpful, thank you
Great video
thank u so much for this.
awesome explanation!
i am saying as a Mechanical Engineer!
Thanks for sharing ☺️
Clear explanation and subscribed ☺️☺️☺️
Your videos are Awesome...👍
Thanks so much!

*underrated*
Effective way to study....
Plzzz come back with fluid mechanics plzzz🙏
Very interesting
I wish, I found these video during my graduation.
I got a doubt. How are the large stress concentrations at crack tip of a brittle materials (in contrast to plastic deformation which reduces localised stresses in ductile materials) a factor for having compressive strength greater than tensile strength in brittle materials?
Maybe I need to work on understanding the concept of stress concentrations.
3:24 if the definition of ductility is the ability to deform plastically then 6:58 shouldn't the ductility on the graph be from yield point to fracture?
How can you define the preyield stiffnes?
Such a great explanation.😍♥️ Keep it going brother. Big fan of yours
Ductile material might not fail due to compression because their cross-sectional area increases with the increase in the stress
does any one knows what software is used to create those animations ?
Which software used
4:10 shouldn't it be fracture at strain of less than 5% ?
This is good
Is rubber brittle or ductile?
3:05 bro KSI alone is already a pretty strong boxer but imagine 19,000 of them 💀💀
I enjoy these videos, however, I fine the music both annoying and distracting!
Perfect
You're awesome
You watch this video a couple times over and you'll have more definitions memorized than after an entire semester on material properties lol
Please tell me 0.2% of what?
finally, there's someone who can explain it more than our university professors
@REPUBBLICA ITALIANA No, the key difference is that visualization is great tool for learning such concepts that most professors don't use effectively.
Sir I want to learn statics and mechanics what kind of maths is required
my teacher uses these videos as his teaching method :D
