Edge dislocation: Slip

Edge dislocation line as a boundary between slip and no-slip regions of the slip plane.

You are by far one of the best Material Science professor's on KZbin. Thank you so much for your time!

[@bijoydeori4469]

agreed

[@nihalmishra1101]

I have never received such precise teaching in my entire life.,really one of the best videos on material science.

I was having doubt in edge dislocation. Thank you professor 🙏

[@vidyutphagetra3804]

The ease with which he explains these concepts is just fabulous

[@gianlucacastro5281]

Thank you prof. Rajesh Prasad! I can imagine how much effort it takes to make a course so well prepared like this.

[@jamesandrews7426]

Even studying at one of the top universities in the world, I find your videos more helpful than what I learn in my lecture. Thank you for well constructed materials. Your playlist are made in a sequential order with short and necessary explanations, fit for students in all areas. Thank you for the effort.

[@weiyz3693]

thank you professor, your explanation is the only one make me understand, and you don't even employ those fancy animation stuff.

[@thukiRC97]

Thank you so much Prof! Appreciate the time and effort you put into this entire course :)

[@n01gaurav]

Have been reading comments from others which are almost 4-5 years old. I second the Professors teaching abilities. Best still!

[@ilahahasanova4263]

Thank you so much, professor! You are such a good teacher!

[@free2learn886]

Yeah, it is very good. you are a very good teacher among the world. The world needs you and your generous sharings.

Sir, your handwriting is too good

[@bhaskargoswamy6873]

Thank you for the guidance.. Also need to know how climb motion works and it's types also.. Plz help me find how it works..

[@mohebbe872]

Thanku sir very nice explanation Understand very well

Sir, how does the bottom edge of the half plane distort its adjacent planes?

[@introductiontomaterialsscience]

The adjacent planes are on either side of the half plane. So the spacing between them is 2d where d is the interplanar spacing. Below the slip plane since the half plane is absent these two plane try to attain equilibrium separation d. This causes distortion near the bottom edge of the half plane.

[@vasanth1996ify]

@@introductiontomaterialsscience thank you sir

[@manohar_08]

Sir why 3-4 paste is not linear

[@Kottam_Yallawa]

👍👍

[@Immsnegidec04]

why did you cut it only half,not the whole...what if u cut it whole...

[@rajeshprasad101]

If I cut the whole crystal and slide it by one step, I just get a slip by one step, but I do not get any dislocation inside the crystal. When I cut only half and slide, I create an edge dislocation at the boundary between slip and no-slip regions.

[@mrKumar-mo5ch]

Why we do cut and how?

[@introductiontomaterialsscience]

The cut is only in imagination, a thought experiment so to say.

[@denghuang9403]

Dear sir, the boundary of ‘slip’ and ‘no slip’ region looks like a plane, extra half plane, in your slide. I cannot understand why is a dislocation line. sincerely!

[@rajeshprasadlectures]

We are dividing the two-dimensional slip plane (not the 3D crystal) into slip and no slip regions. Therefore the boundary is a line (and not a plane)

[@ravithakur0041]

Any IIT Delhi student seeing my comment ? Pls reply asap. Its urgent.
