Damn how can a 30 min video be way more innformative than my profs 2h lecture? Thanks a lot man, we students really appreciate what you're doing!

[@ClaytonPettit]

Thank you so much :) I'm really happy the videos have been received so well as my students typically fall asleep haha

Because Universities hire professors, not teachers. The best educators are professors and teachers simultaneously. The system is broken.

goat, imma bout to make the greatest academic comeback in history

My whole life made sense in 30 minutes, Thanks a LOT!!

[@k.w5804]

You sir sure have a great way to explain things and to keep the viewers engaged. Loved it.

[@nicolasramirez3944]

Amazing lecture and teaching style! So clean and well presented. Thank you!!

[@Pauldyke]

Thank you so much, Clayton. You really have no idea how this video has helped me.

[@mjaysaratchandra8196]

This is incredible!! A very high level niche subject taught very well❤🙏

[@yuribezmenov6187]

Thanks man, perfect explanation.

[@franciscobrandao4832]

Amazing video, great work!

[@bobo_ism]

Very clear explanation on the transfomation bet. the global and the element attached natural coordinate system

[@killer198806222]

It's amazing how you can make it so easy to understand

[@yahiaroukaibi4044]

thank you so much dr.Clayton

[@ingGS]

Fantastic explanation! Thank you professor.

[@SadiaAnumStudent]

Thanks alot, It really helped.

[@kunal.9587]

Can you upload more videos on fea? It is very helpful.🙏.

[@dilipkumarjothi848]

Great video, thanks for simplying the topic.

[@lucaszampietro5844]

Absolutely amazing!

[@yasminnoory2388]

all i can say its just god bless you thanks alot

[@rutledgefogel4738]

Dr. Clayton, I am studying FEM theory at the graduate level and your videos are supplementing my course material very well as in class it's hard to understand. Do you recommend any other videos or supplemental material to make theory and applications of that theory easy to digest and access?

[@AJ-et3vf]

Great video! Thank you!

[@antolethron]

What was the previous video? There are only five lectures in the FEA Theory playlist and this one is first on the list.

[@retiredreplicant.2195]

Fantastic job. Thanks.

[@shivangbhatt7175]

Thank you so much sir 😇 This is very informative video 👍

[@mahmoodsaeed4175]

Thank you, Professor. I was wondering if you give an access to the lecture slides as they are great!

[@dsaun777]

can you show how you derive the shape functions

[@khiladikumar491]

could you solve some problems on shear force , bending moment in beams..,frames

[@blackguardian89]

Very good lectures! You got a subscriber :) I hope you'll make more videos on the subject of FEA soon. Just wondering - would you devote a lecture or two on the 3D finite element analysis?

[@ClaytonPettit]

Thank you so much :) and yes the plan is to make more FEA videos soon! Once the Engineering Statics theory videos are done (about 1 week), I am going to make videos for Solid Mechanics (2ish months), followed by FEA (2ish months), then Plasticity Theory (4ish months). While doing the FEA videos I plan to redo the current videos (they are old and the audio makes me cringe haha) then add a considerable amount of videos dealing with topics I did not discuss while teaching the graduate course such as shell elements, beam elements, 3D analysis, thermal modelling, XFEM, SPH, etc. Sorry for such a long answer but I wanted to let you know what is in the works :P have a wonderful day :)

[@elhammo.9408]

is was helpful one, can i ask to zero thickness interface element, please?

[@shivangbhatt7175]

Sir what programming language will be the most suitable to program this element and related problems? My inclination is towards VBA but I am ready for a change.

[@wernhervonbraun4222]

Hi Clayton, I am learning about FEM. Which video should I start from? Please suggest.

[@ofiradi4775]

good video. thank you

[@alehegntesfaye5235]

Interesting and very active lecture. Sir have you given detail lectures on hexahedral elements ?

[@justintomko1638]

This is a great video, I am looking at my text book and it is using a different Jacobian formulation [dx/d_zeta, dy/d_zeta; dx/d_nu, dy/d_nu] is there s significance to the order that it is in?

[@tonywang3070]

what the meaning of "t" in (3:19)

[@ClaytonPettit]

The thickness into the page :) the integral is technically over the volume of the element but since we are assuming a constant into the page thickness we can replace the integral with the constant t instead.

[@nilso3719]

Hei, just wondering if you have any videos with Linearized buckling analysis, and the math's for explained it? I am a Danish engineering stundet

[@ClaytonPettit]

Hi! I did an example in the FEA program ABAQUS in my live lecture video (kzbin.info/www/bejne/mYm5l36ei756a5I) but have yet to make dedicated videos on the subject. I plan expand my FEA video series to after I am finished with my solid mechanics videos :P

[@nasosskaltsas9890]

Hello professor, can you explain how we can calculate the middle matix in the B-matrix [dξ/dx dη/dx 0 0 ; dξ/dy dη/dy 0 0 ; ....etc ] ?

[@ClaytonPettit]

In essence you calculate the Jacobian, inverse it, the call the required entries into a new matrix :P I show how this procedure is conducted in detail in the following video: kzbin.info/www/bejne/mHSvqIB9YsaeqZI. Hope this helps :)

[@nasosskaltsas9890]

@@ClaytonPettit So, the whole B-matrix is equal to the inverse Jacobian?

[@ClaytonPettit]

@@nasosskaltsas9890 No, we use the inverse of the Jacobian to calculate the components of that middle matrix within the B Matrix

Great lectures. Thank from Imperial College😭

[@riccardouras8677]

I LOVE YOU

[@xerenityapexlegends3940]

EDIT: the video is correct, i misinterpreted Original question: aren't the isoparametric shape functions incorrect? in other places I look, N1 = [n*E*(1-n)*(1-E)]/4

[@ClaytonPettit]

The shape functions presented are correct :) the shape function you listed is for a 9-node quadrilateral element (referred to as a biquadratic quadrilateral element) while I presented the 8-node quadrilateral element (referred to as quadratic quadrilateral elements) as they are more common in FEA programs :P This is a great question and I hope this explanation helps eliminate confusion :)
