Nonlinear FEA in shell design

[@kolavithonduraski5031]

thank"s for the 'english voice over' 😊👍

[@Enterfea]

I'm happy that you enjoyed the video :)

[@neocentengineering5624]

@Enter FEA, Appreciated, your single trick (Non-linear) solved my all the corporate problem ( Maximum stress always with vaccume_Static equipment FEA)...

[@Enterfea]

I'm really glad that I could help you out! All the best!

[@bloodyzohair]

Now this makes me more interested in Non linear shell fea ... I am already a follower of your website. Thanks a ton. 🙂

[@Enterfea]

Sure Zohair! Nonlinear FEA of shells is super cool, and I feel there aren't many folks that do those things. If you are interested in the field, just give it a go - I don't think that the field will change in the coming years (or at least I hope so!).

[@PetarPetakov]

Great lecture and thank you for doing the voice over! Your work is extremely helpful!

[@Enterfea]

Thank you Petar! I'm glad that you like it :)

[@MrAntreaspaok]

Thanks for this !!! I am passionate about FEA as well and I'm glad I see more people into this field too

[@Enterfea]

Hey Alan! I'm glad that you like the video. Indeed FEA is an awesome space to be in if someone likes engineering :) All the best!

[@teachyourself7374]

Great presantation, ı can see you are good person. I wish you all success. Best regards.

[@Enterfea]

Thanks! I really appreciate this :)

[@cleisonarmandomanriqueagui7502]

I would love to work there ... great conference !

[@Enterfea]

Thanks Mate, I'm glad that you like it ;)

[@nicolasramirez3944]

the comment "can use membrane theory ie if now its tuesday then its 70 MPa" cracked me UP lol

[@Enterfea]

Thanks Nicolas :) I'm really happy that you like it :)

[@xutaosun2364]

VERY GOOD!

[@Enterfea]

Thank you ;) I'm glad that you like it :)

[@ivarkjelberg1317]

Nice talk, and that justifies why I'm not eager to enter the Shell FEA in detail, too much work and engineering experience to reduce the detailed CAD models we receive, and to perform good trustful FEM models, I'll rather leave that to you, the specialists. But for the multi-physics of "small" devices modelled in full 3D, linear as well as mostly highly non-linear, with structural, HT, CFD, AC/DC, RF, Optics and why not some chemistry, well I feel far more comfortable, and I know when to trust my models :)

[@Enterfea]

Hey Ivar! I guess we all have our "sweet spots" when it comes to what we feel comfortable doing. For me, the "big switch" was to ender pressure vessel design, as I was never trained in this... but in the end I've learned that this is all the same, just documents look a bit different :) It looks to me, that you have a pretty fun job Mate! That's awesome :)

[@drury2d8]

THANK YOU FOR THIS LUCAS!

[@Enterfea]

Sure thing! I'm glad that you like it!

[@drury2d8]

@@Enterfea Where can i get the theory behind this for a basic overview?

[@Enterfea]

@@drury2d8 Hey! There is a LOT to cover I'm afraid... You would have to read about stability a bit (like here: enterfea.com/what-is-buckling-analysis/) and about nonlinear FEA in general (enterfea.com/how-to-tackle-nonlinear-finite-element-analysis/). But my approach to teaching this is rather practical in nature. If you would like to get into the equation derivation and stuff like that this is tricky... I would suggest prof. Rotter work (I think he wrote some articles with Sadowski, that are mathematical in nature). Of course the Timoshenko work will cover nice "origins" but obviously there is nothing there about nonlinear FEA :) If you will ask more precise questions about what you are interested in, maybe I will be able to help you more with your search! All the best! Ł

[@peeolo]

Tnks lukas for this material and for the English voice over. I'm not so good whith polish ;)

[@Enterfea]

I'm glad that you like it Paolo :)

[@dmytrosky]

You the best!

[@Enterfea]

Thank you, I'm glad that you like the video :)

[@kamsince86]

Very informative! Thanks a lot for this. Please suggest how do you plot load vs strain chart in FEA platforms (say RFEM).

[@Enterfea]

Hey! There is no easy way to do it in RFEM... sadly this is a software not intended for such analysis. Sure you could do it "manually" but that would require calculating the same model with higher and higher loads to get the "points" on the chart... I would not advise such an approach!
