Why does critically resolved shear stress in a single crystal matter when overall a polycrystalline material has grains in all sorts of directions? Like, at the tip of the void that propagates id expect the crystals to be in all sorts of possible directions. Thanks for the videos
when its INTERNAL crack yes, it should be 2.5*10^-4 . but as the question says,its at the tip,so u should divide it by 2. as internal cracks are "2a" and tips are "a"

you are the best ,I crawled through the whole of internet to understand this concepts before coming to this amazing explanation
you literally saved me the night before my exam tomorrow morning thanks so much :')
29:08 so that's what happened to the T1000 in the "asta la vista, baby" scene.
you help me a lot.. thank you so much
very nice explanation
Thanks a lot, ma'am.
18:10 why we didn't convert mm to m
Thank you for this video, it helped a lot!
Will you do more of Materials Science or are you done with it ?

Thank you 🫶🏼
16:52 why is internal crack length is one half of the surface crack length
Glass is Glass... Glass can Break: Brittle Material
Where can i find the other chapters of material science????
MAM you are so great , helped me a lot . I sub the channel . Do you have patreon ? really would like to support the channel. Love from INDIA.
Why have you taken 1.25*10^-2? at 12:14, should it be 2.5*10^-4?
internal crack length, "a" means half of internal crack length.
when its INTERNAL crack yes, it should be 2.5*10^-4 .
but as the question says,its at the tip,so u should divide it by 2.

This is the link to the video at 27:00 for anyone interested
