Dislocations in motion

[davidcool24]

thanks for the video, 0:09 see that expanding loop in the centre and finally breaking apart. I guess the line tension then exceeds a maximum but I've not seen any "maximum tension" theory!

Anyway, it's beautiful.

Well, dislocations are certainly not called like that. But they have a lot to do with it. Please, read the text on the page linked below.

So the black worm like lines are the deformation lines?

[kotecky]

Certainly both. Consider this image: 3.bp.blogspot.com/_52ad6YS2zrs­/TEtsH8K2GbI/AAAAAAAAAIo/81kGM­s30Gj8/s400/4.jpg

And read for example this page: moisespinedacaf.blogspot.com/2­010/07/edge-and-screw-dislocat­ions.html

woul that be an example of edge or screw dislocations?

@BoltFactor Actually Now I'm a Senior In Material Engineering, and I know all about this stuff now : )

Wow, this is really nice and interesting.

Do you have the detail on this ? What metal, temperature, cold-worked or not...

Thanks for the video !

[davidcool24]

@JulienDAmours indeed this would be interesting

[hanafy88]

ok thanks (by the way i'm in Materials Engineering, i could understand :)

[hanafy88]

Can u plz give a small explanation of what this is  ??

[kotecky]

Oh, it would be rather a long story. You'd better read more in wikipedia. Look for "Dislocation".
