Sir, Area under the stress-strain curve within elastic region is not "Modulus of elasticity" as you have explained. The area under the curve within elastic limit is "Modulus of Resilience or Resilience", or in other word we can say, strain energy stored (absorbed) in the material within elastic limit are know as Resilience.

Actually the slope is E he might be reffering to

But at point D why do we need to reduce load ? Why not keep on increasing load 'P'? Is this because we want to study true stress (necking of specimen)? What if we keep on increasing load? Does the fracture will happen too early and we will not able to know what is going to happen during necking?? Please elaborate

i cant find better explanation in stress strain curve other than this lecture, awesome explanation especially from point D to point E dip in engineering stress and increase in true stress, excellent explanation sir,...

Very clearly explained everything.. bravo!!

Awesome.... Video on Stress-Strain Diagram... 👌

Great Sir u explained it very clearly ❤

Except for that Young's modulus part, whole video was great and removed almost all my doubts.

Superb explanation in english with simple words...😊😊

I am preparing for GPSC and I will pass it definitely

Awesome video SIR........ It cleared all my concepts........... That's a great job u are doing there..................

Area don't becomes Young's modulus. It's the slope. Area under stress-strain curve upto proportionality limit is called modulus of resilience. Like Young's modulus, shear modulus and bulk modulus, modulus of resilience is also a material property. It could be defined as the resilience per unit volume.

No, in this region compressive stress to the corresponding strain is a constant. This ratio is called as Young's modulus....and this portion also called as Hooke's law or proportionality limit....but we can get modulus of resilience up to Eleatic region....

Superb, i love him.

Thank you sir , very useful tutorial 😊

Nice one sir.. Really useful.. Thanks a lot

Very helpful... hoping for lots and lots of videos on engineering subjects.

Super explanation sir.... great

grate explanation sir. make new video for the other subject

Excellent Teaching sir.....

Good explanation 👏👏👏👏

great videooo!!

The Teacher has good knowledge and ability to teach in a professional manner. Thanks

Well explained sir

super, sir. thank you.🙏

dear sir the area under the curve is modulus of resilience up to elastic limit and modulus of toughness for the entire graph

brilliant explanation

How do you calculate ultimate tensile strength from yield strength?

Sir, how come area becomes Young's modulus and not it's slope???

The area under the curve upto proportional limit is called resilience. It is energy stored up to elastic limit.

I think, After point D and necking material starts acting like soft material consequently decrease in internal resistant to load and therefor stress goes down.

The area gives the energy whereas the slope gives the value of E.

Area gives the value of modulus of resilience

Thank you Sir :)

Thank You

beautiful, I understood everything, thank you

Thanks, if you can make video about stress triaxiality and ductile damage please

Great

Awesome explanation..

Do the stress - strain curve only for steel material ? What about other mtrl like timber??

Nice lecture...#MechanicalTutor

The necking formation gets start from the upper yield point to lower yield point that is why the slope gets down because heat get increase and sudden cooling makes the body Harden at point c after that the body get more load by the UTM till D that is the maximum load bearing capacity of the body after the the body gets fracture due to continuous increasing load..... Please tell why the slope gets down from B to C

Thank you sir

I was happy to find a complete SOM course, then I watched this video explaining incorrectly one of the simplest notion of stress-strain curve. One can do mistakes, but publishing a video online, so I guess without watching it before, with such mistake is not acceptable and it decredibilizes the entire course.

Useful

Very nice video #caissonpoint

the area is not Youngs modulus but the slope is. Please teach these subjects seriously..considering each topic very clear. Otherwise it will be disastrous for students.

nice

kya padha rhe ho yaar .

Last me load reduce hora h to strain ku badraha h??? X axis pr

Are ye btao young modulus ki definetion

why there are two yield points in stress strain diagram ?

So Hooke's law is applicable only till proportionality limit... Or all the way up to Elastic limit...

Till proportionality limit

Meaning of stress

sir its became complicated ,expplain simply

Sir area give strain energy not E

He is saying wrong at 4:14 . the slope of the curve will give us the young's modulus.

Is there any reason

Why stress after point c is increasing

Area under the curve O A(1/2*stress*strain) is not young's modulus .......Young's Modulus is Slope of the curve(stress/strain)

why we are delaying the fracture point ??

@swapnilraval3048

Because we want the perfect value of load at which it is really breaking.and we can't get it if we are keep on applying load by universe testing machine as we were applying before fracture point.so basically we are micronising the intenisty of application of load to get the perfect result.

but take load as F.

if ur teaching is not connected to mass students then ur show off english is futile. that is the reason of success of alakh pandey sir

Point B should be elastic limit as it shown in ncert

sir. Where is the ultimate stress in the true graph?

@ranjithmamindlapalli700

at D you can find ultimate stress which is nothing but the maximum stress the material can give to resist deformation

Beyond elastic limit permanent deformation takes place A should be praprotionality limit
