[@pranavkulkarni1414]

If elasticity is higher, stiffness is lower. Because stiffness is resistance to deformation. More elasticity means greater the tendency of a body to bounce back from deformation. So elasticity allows deformation to take place. Stiffness prevents deformation. So if slope increases (ie ø tends to 0° or slope tends to infinity), that means strain occuring is less for higher values of stress within elastic limit (which is what stiffness needs).

[@maheshkanoji3593]

Elasticity does not helps to deformation takes place. It is only the ratio between stress to strain. If you see at the unit of elasticity it is N/mm^2 and stiffness unit is N/mm. Hence both are not opposite. Elastic effect is measured on cross section area while stiffness is the only increase or decrease in length due to external load. Please correct me if you have difference of opinion.

[@pranavkulkarni1414]

@@maheshkanoji3593 yes you're right. I didn't say elasticity allows deformation. I meant to say in case a large deformation takes place in a body, the material will return to its original state due to its elasticity. Take a typical rubber band for example. A large amount of deformation takes place for a small load or stress. But it still comes back to how it was before it was loaded. This points towards a stress strain slope with a lesser slope (and hence Young's modulus is less). But a stiff material will allow lesser deformation for a large load. Take the iron pillar in India (excuse my lacking general knowledge). It wouldn't move even a millimetre if you applied even a large load. That is high stiffness. If a material does not move with large amount of stresses induces in it, that mean the slope of the stress strain curve within elastic limit is more towards infinity (which means Young's modulus is more). So my point is, the more elastic a material is, the less stiff it will be (but the lecturer in the video says they will both be high). Or a large Young's modulus means lesser elasticity and greater stiffness.

[@siddharthvasava4185]

Sir, great video with simple explanation. Sir i have a doubt which is not cleared in this video, what is the nature of material between point B (elastic limit) and point C (upper yield point) ? Is the material behaves like elastoplastic material or completely plastic material? I am very thankful if you clear my doubt. And thank you soo much for upload excellent videos with simple language explanations.

After yield point, the dislocation entanglement kept on going; but at that point, necking causing the lower value in the strength.

Necking starts after ultimate tensile strength

Sir elasticity ends at elastic limit and beyond that plastic deformation takes place. But u told that beyond upper yield point plastic zone starts.

Bhai aapne yadi sare lectures dekhe h to Kya sabhi lectures se gate ke questions ho jayenge Kya ? Yadi en sabhi lectures ke concept clear ho to ?

[@vishwajnaacharya1584]

Sir, In this video you have explained Resilience twice...that is once in main stress strain diagram and 2nd time in a separate diagram after proof resilience...I'm little bit confused with those two...can you please clear this out

[@insanegamerfeast2873]

In stress strain diagram it shows modulus of resilience and if we talk about the load deformation diagram here we focus of definition of both like proof resilience is energy absorb upto the elastic limit and simple resilience is energy absorb within elastic limit means lt will always be less than Pt B And in stress strain diagram we talk about energy per unit volume and in the other diagram we talk about energy so both are different

[@nandikdas2144]

Sir, you told distance b/w UYP and ultimate point represents ductility. But previously you told UYP is the failure criteria for ductile material where permanent deformation takes place(yield stress). I'm unable to understand this. Please clarify my confusion Thank you.

Sir theory of failure k bhi bna dijiye video .. aur curved beam ki

[@sahildaheriya688]

sir in stress strain curve of ductile material, till elastic limit material behaves as a elastic material and from upper yield point yielding gets starts, so sir what happens in the material between elastic limit to upper yield point? sir what the phase between elastic limit to upper yield point signifies?

I have a doubt In normal tensile load oblique plane how creat?

[@priyanshuchauhan655]

One doubt --In brittle material the area under st-strain diagram up-to elastic limit is called Proof Resilience OR Modulus of Resilience????

[@nitinkhalkho8779]

It will be called modulus of resilience, if it would had been for elastic limit it will be called proof resilience

sir in previous lecture you proved that if youngs modulus of elasticity is more material is more rigid and in this lec you proved that if youngs modulus is more than elasticity is more... please explain

[@kshitizarora6880]

Its a same thing...elastisity matlab...body apni original shape m vaapis aajeegi..jo ki rigid bodies m dekhne ko milta hai

[@harshadamahadik7853]

While drawing stress strain diagram for ductile material, our basic assumption is that the material is homogeneous and isotropic. So, how come strain hardening comes in the diagram ? As per the explanation in video I get that material should be non homogeneous for a strain hardening to occur which is in contradiction with our assumption. Can you please explain?

[@beginner828]

After yielding, material inner structure changes and creates interlocking situations and work needs to be done to overcome those interlocking forces to deform the material further.. to the point you wrote..to reply more specifically in simple words.. yes the assumption is that the material is homogeneous when you start the tensile loading, during loading after crossing yield point, obviously the material deforms.. which means its inner structure changes.. hope this helps. I recommend you to see Sir s previous videos in sequence .. have a good day.

[@habeeb_a]

@@beginner828 nice explanation bro

it will be homogenous within the limit of proportionality, after that , it changes, your doubt becomes true

Sir yield point jo h failure h ductility ka to kyu ductility increase horahi h agar distance increase karate h upper yield point se ultimate tensile point tak. Sir aap ne ek vedio me bataya tha ki yield point pr ductility failure hoti h

[@muhammadsajjad8527]

One thing is confusing. In some previous lecture sir said if the value of young's modulus increases, material will show rigid behaviour. Now in this lecture sir is comparing it with elasticity. If E increases rigidity/stiffness increases then how can the elasticity be increased? If material is more stiff it will resist the deformation... If anyone could explain it, pls?
