Burgers vector of a dislocation is constant along the line

[@ShuvamNayak]

Sir, in which video did you teach about Franks's rule? I am not able to find it.

[@IITian_shubham_shekhar_rajput]

The conservation of the Burgers vector at dislocation nodes is called Frank’s rule. Similar to the Kirchoff’s law describing that the total current flowing into a node is zero,

Sir what is node and it's physical interpretation in crystal (atomic sc.)

Is there a textbook which should be used to follow along with the material?

Very nice, Sir
thank you!

[@rc-mechanical3596]

Thanks

[@flavorsums53]

In this video I got confused with burgers vector direction because in earlier video it is opposite

[@lynaaline365]

thank you so much sir

[@introductiontomaterialsscience]

Most welcome

[@missionbeingmech9550]

sir in previous video u discuss about constancy of burgers vector but here u change the direction of burgers vector in accordance with unit vector why??

[@introductiontomaterialsscience]

I am only changing the unit tangent vector but not the Burgers vector.

[@experTUTchem]

@@introductiontomaterialsscience sir u reversed the tangent vector,and then u also changed the burgers vector
Can u explain why?

[@introductiontomaterialsscience]

@@experTUTchem A given Burgers vector is associated with a chosen tangent vector. Tangent vector can be chosen in one of the two possible orientations. Resulting Burgers vectors will be opposite of each other.

[@ShuvamNayak]

Is elastic energy that you calculated is what is known as Franks's Rule?

[@ShuvamNayak]

@subbu saravanan He did mention about Frank's rule. Also in some previous video on Burger Vector when discussed in brief about Frank's rule.

[@connor8875]

Do you know of a companion textbook to the course?

[@ShuvamNayak]

@@connor8875course doesn't mention companion textbook. I generally don't follow any book as this video's are sufficient. You can try your luk with your College's recommended book
