There is no difference in the result, but at 17:26 I believe that vector A (slip plane vector) should be (111) and vector F_s (slip direction vector) should . Unless I am confused. Which is a possibility.
I have a question. I don't understand why the slip direction is the same as the Burguer's vector direction in screw dislocations. The slip direction is perpendicular to the dislocation line , but the dislocation line is parallel to the Burguer's vector in screw dislocations. So I don't understand this.
Why do take the other angle between the slip plane and the force direction... Should't it be angle between the slip plane NORMAL and the force direction instead?
Hi! Yes, if I misspoke I apologize for that--it is easy to get tongue-tied with these definitions. In the textbook we use (Callister and Rethwisch) for this class, phi is defined as the "angle between the normal to the slip plane and the applied stress direction." I believe it is stated correctly on the slide.
@chrisian Young @@tonyacoffey5568 Because we are measuring angles in different planes. If normal to slip plane, slip direction and applied force direction lie in a plane, then phi and lambda would be compliment angle, otherwise each angle should be calculated by vector dot product only.
Very nice video and explanations. I see you are using Callister slides or at least drawings from the book. Is it ok for the copyright? I ask because I am also using this book, but I have refrained from making videos containing their graphics because I was afraid of copyright issues. Did you ask permission, or is it just ok to use their graphics or maybe you just take the chance? In such case, no worry, I won't tell. Thanks.
Prof. you missed so many points in between as if you are rushing through the slides... For eg CCP has 24 possibilities of slip system but only 12 are chosen? I wish if you take a moment provide more details it would be more helpful prof. You may check prof R. Prasad videos on UA-cam for details
This was completely useless in figuring out how to actually find generic slip systems and which are activated. Apparently this knowledge is forbidden because I can’t find a single source online that explains it.
Not all heroes wear capes, and you are one of them!
Perfect! This is certainly very helpful and you are a great teacher. Thanks
I was totally confused by the things my teacher said and the book I've read. but now suddenly everything makes sense! good job.
u said in your profile that your videos must be boring. yeah maybe for the public but not for me.. ur a blessing

i think u right my dude
Thank you from Turkey 🇹🇷🇹🇷
It is really helpful. You are certainly a great teacher.
Thanks!
Amazing video! Extremely concise and informative
Fantastic informative video, thank you so much for making the video and sharing it!
Fantastic and appreciable,
It's really simple and comprehensive.
Wonderful job....
i have an exam tomorrow and i couldnt ask for more. Thanks mam

So I don't understand this.
In the picture of the single zinc crystal, why do we SEE the dark bands? Was this an X-ray of a thin section?
Thank you fo this video, it was very helpful.
really very great considering this little details
Thanks for sharing
Why do take the other angle between the slip plane and the force direction... Should't it be angle between the slip plane NORMAL and the force direction instead?
You saved my life, thank you so much!
In 17:15 example (although it won't affect the final answer), I think lambda and phi should be reversed
how we find no of slip plain without seen diagram for example {111}plain and direction (110)?
Isn't phi the angle between applied force and slip PLANE normal?

Very Nice
Thank you so much!!!:)
Hi,what gonna happen to the sample if the angle of slip direction is varying?and thanks
you are wonderful, thank you so much

Really really really really helpful. Thanks a lot!
Sorry I might be dumb here but I only see 9 possible slip systems there at 5:10...can someone explain better?
thank you, it was very helpful.
this video is awesome.Thank you madam.
Thank you
Thank you. It was very helpful.
very nice video :))
It was very helpful. Thank you! :)
Thank you.
Could you make a video about the dislocation in amorphous materials
Many thanks
thank youuuuu!!! this helped me alot
Life saver thank you :))
Thkss
If I've got these videos back in 2015(My second year).
thanks sooooooooooooooo much!!!!!!!

Thanks ma'am
Thanks
It really good for me
i wish u were my teacher!!
Can I have pdf notes of material science...pls mam
Well, i cant contact with you mrs Coffey

lol ....same here and i have an exam tmw
yuo are prettiy
Vay mk karıya helal olsun
ı didnt understand a single word. ı think all the lattices things are bullshit.
