In this Covid time ,When there are no practicals ,only online classes. These lectures helped me a lot. You r an amazing proffesor. I want to thank you from the core of the heart. Thank you so much sir ❤️ You are the best teacher.
Although your English is a little hard for me to understand! But u r the only one of the techers who I have met can explain it simply and clearly and not like another teachers, who just want to read the conclusions from the Powerpoint ... thanks a lot, sir
Sir my doubt is in slip approach as u mentioned the edge dislocation line was caused due to the slip ie burgers vector and then established the relation as b and t are perpendicular. But in case of screw dislocation u mention b and t are parallel but how come the edge dislocation line be parallel to burgers vector when slip itself is responsible for the formation of edge dislocation line it, should ve been perpendicular to slip .. ?
bro did you get the answer ...............i too have the same question?? how is it possible that burgers vector is parallel to tangent vector......because burgers vector itself is the reason for dislocation line moving in perpendicular direction
@@saicharan9174 Professor is right, i think you are confused by the Vector notation on 'b' -> (the line arrow on the letter b) which is horizontal line. Just follow the movement direction (y direction)'I', not the vector arrow on top of b (x direction) so 'b' and 't' are parallel, both are in the y direction

Applied stress can be of any type (tensile/shear) and in any orientation. But only the shear component of the applied stress on the slip plane in the direction of the Burgers vector is effective in moving the dislocation.
The probability in BCC to slip is more than FCC as BCC has 48 slip system and FCC has 12. Also denser crystallographic plane become the slip plane, plane where slip occurs contrary to what we think
After years of trying and giving up on this topic, finally I understood it thoroughly, great respect and thanks to sir🙏.
i swear you helped me a lot to pass my exam....thank you sir

Where are you from ?
For me his English is great and to simple to understand.
finally i got clear concepts about screw and edge dislocation through this amazing lecture series
Explained some fundamentals that my uni lectures missed, Thanks!
You are a wonderful teacher, sir
You r the best sir..
It is a good explanation. Thank you
youre a king for this one buddy
Thank you Sir.... Beautifully explained 😇😇❤
What an amazing teacher
Thanku sir for this great explain

Hocam süper video teşekkür ederim :')
Thanks 💛💛
thanks a lot sir i cannot understand it froim the nptel course i am doing now but i understand from u
What the difference between dislocation in cubic structure and non cubic structure?
such a nice video ! 🌼
Excellent explanation....
Is the direction of burgers vector and Shear stress applied same?
Applied stress can be of any type (tensile/shear) and in any orientation. But only the shear component of the applied stress on the slip plane in the direction of the Burgers vector is effective in moving the dislocation.
Thank you sir, nice explation
Thank you sir🙏
Very helpful 👌
Tq sir Happy teacher day sir
Dhanyawad Sir
sir aap mast dikhte ho maza aa gya 🤤🤤
Wonderfulll
Which dislocation movement is easier in fcc and bcc crystals and does the most dense packed planes exhibit resistance to the dislocation climb ???
@ Deepak Rao: When you say which dislocation movement is easier, what exactly do you mean?
The probability in BCC to slip is more than FCC as BCC has 48 slip system and FCC has 12. Also denser crystallographic plane become the slip plane, plane where slip occurs contrary to what we think
I mean to say slip planes.
M
what is b and t...haaaa
b is bugers vector and t is dislocation line
