Lecture - Fracture Toughness

[@ihabullahkhan7734]

A crack has one tip, while a flaw has 2 tips. Imagine you have a crack with crack lenth 'a' and Crack Tip 'A', so for an internal flaw it will have two crack tips and thus the length of the flaw will be equals to 2 times 'a' (Crack Length) that is why its '2a'. Thank you for the informative video. 😊

i have a stress range of 180 applies and want to use this values to get Y. how ?

I have question, so the fracture toughness is higher with longer/bigger fracture? I am a bit confuse here

This is amazing, 2 minutes in and I understood certain concepts that I have been having a hard time grasping. I have one question; why is K larger in plane stress condition than plane strain condition for the same material?

I've watched the whole video as part of my solid body mechanics revision (the notes provided by my lecturer are quite crap). I greatly appreciate the content of this video, thanks for sharing!
