Extremely helpful for my current project in surface acoustic wave-induced fracture! Thank you!

[@larryclark9380]

Great content. Helps me with a class I am taking. Thanks. I will review your related videos.

Great lecture and very clearly/simply explained, thank you. Also nice Sauron ref 😂

[@TheBomPE]

Glad you liked it! I never pass up a LOTR reference. Thanks for watching!

Mechanical Engineer here (P.ENG.) ….love the content from your channel!

[@TheBomPE]

Thank you so much!

[@tejmachhar4903]

Superb work. You made it easy to understand. Need more on fracture mechanics from your end to learn.

[@TheBomPE]

I'll definitely keep that in mind, and if I have a chance to teach an elective or something, that will help me reserve the time for developing a series like that. Thanks for watching!

@@TheBomPE Watching your videos reminds me of a dynamic professor who used to teach us at the university. Still, there are few people having such clarity of thoughts. With this, I would like to ask what lifestyle do you follow? Just reading more and more doesn't make one genius.

[@TheBomPE]

I guess I just love the material I teach. I feel like I've been gifted by God with certain intuitions and passions, and I love teaching. I've also done a fair amount of mechanic work in my time, so that helps inform me about how some mechanical things tend to be done. I enjoy math and tackling difficult but useful problems.
But I'm a pretty plain husband and father of 2 though, when it comes right down to it. :)

great lecturer sir
I want to ask one question what is the effect of temperature on fracture toughness of material,while going high temperature fracture toughness decreases compared to room temperature test.

[@Justinpark12]

Increasing temperature accelerates the diffusion process of atoms, accelerating crack propagation.

[@fufufufu951]

So helpful lecture!

[@fidansmaili6306]

Great video Sir!
I want to ask you if you can explain in other videos the Kitagawa Tagahashi diagram and it's relationship to the fracture toughness of materials!

[@TheBomPE]

I will be doing an example video that I will post this week, and it gets into that diagram. Thanks for your patience, and thanks for watching!

[@anggitwahyuardianto3570]

Is there a summary of materials in Indonesian?

[@TheBomPE]

I don't have any Indonesian references I can offer, I'm sorry.

[@closetdoor123]

Is it habibi's theory?
