the closing was good.After Y2 stress increases because dislocation entanglement takes place which increases the stress(or resistive load).BTW u very clearly explained what is restive load and stress.

Thanks for this explanation but ,Sir how you say strain is the Cause and stress is effect? Stress is (Force / Area) and force is applied by external sources. Means force will be the Input . Similarly strain is the effect which gives us ratio of elongation to their original length . That means elongation should have result due to input force per specific area .It seems strain will be Effect. Strain is behavior or property of martial while goes to applied Input force . Sir please explain the doubt.

Sir if atom has that much power of bonding then why they cant retain initially at plastic state . Or why doesn't that power of bonding consume at plastic zone to retain it? I am talking about up going curve at " U" point.The bonding power once which fails to retain yielding or cause to plastic state then how it generate again to increase stress. Sir please explain the doubt.

Underrated channel, man. Epic video for real. Thanks a lot. I just got one question though. What is the region between E and Y1? If the elasticity stops at E, then doesn't it also mean that plasticity starts at E? Can you please explain the difference between leaving elasticity and entering plasticity? Thanks in advance.

Hi sir, Video is very clear in all aspects (good explanation), I have a doubt, speaking about ductile material, whether we design based on yield strength? which yield point we consider (upper or lower)? If it is lower then y not upper(vicevesa)? yield point is in plastic zone then when we release load it will not regain to its position, still we prefer yield y? Could u help me in resolving

Sir I have doubt about calculation of Young's modulus If ultimate tensile strength of material is 178 MPa Total strain or ultimate strain is 0.098 E=178/0.098 The above is correct or not
@RohitChowdhury_sajaysaini4 жыл бұрын
No it is not correct. You can not use this linear relationship (Hooke's law) beyond proportionality limit.

@rzgarasadd23954 жыл бұрын
thank you so much sir very usefull , but i coudnt understand from strain hardening ,how stress more increase when material lacked bonds ?
@RohitChowdhury_sajaysaini4 жыл бұрын
At the upper yield point bonds breaks And the stress actually drops from upper yield point to lower yield point. Then the rebonding takes place with the new neighbour atoms. And that's when the strain hardening starts. And thus the stress induced again increases upto the tensile strength of the material. Thank you. Dear if you study material science subject things will get more clear. This lecture of mine is just a preliminary one where I assume that a student does not know any thing about dislocations, slip system, plastic deformation etc:- In my next lecture I shall discuss the above mentioned topics from material science approach.

sir, facture stress is above yield point or below yield point.?..... and why???
@RohitChowdhury_sajaysaini6 жыл бұрын
Fracture stress is above yield point.because its the region where material fails or breaks ..but yield point is not that point where a material actually technically breaks...it is a point where plastic deformation starts and quite a few its not desirable...and for ductile materials we consider it as a failure point..although the material actually has not broken...so failure not only means breaking..it simply means that we can not use it any further
