Step4: wrong once check

That was a lot helping, thank you !!!

High five, I use the same way to write big X as well

Thanks for the lessons. How to calculate the delta d?

who got shot at 8:47?

You are all over the place dear.

how to solve for the u(x) , if instead of u(0)=0 , say u(L) =0 , or for any condition when x is not zero, how to solve that in Matlab?? any help

nice demonstration

My god. Why isn't there any sound.

Thanks a lot!

typo where stress_23 was mentioned twice

no sound :(

This saved my life! Thank you!

Insightful information, thank you for posting. I know it's a 6-year old video, but a small tpyo, at 5:05 the value for 0 for Kronecker-Delta is when i not equal to j.

thank you for the video, finally I got some clarification on what bilinear actually means

Three things, and I appreciate your feedback!: 1) thanks for the video! Good info! 2) I got a little confused about your notation, but I knew you meant the plastic strain tensor (second rank) not the plastic strain (zero rank). 3) My question is this, for granular materials, I believe plastic strain was caused by LOCAL shear loads only, so if one were to take the resolved tractions onto a given slip plane, then one would then find that all the principal direction’s normal loads WOULD NOT contribute to plastic deformation, but instead ONLY shear loads WOULD cause slip / plastic deformation. Put another way, instead it would only be the external load’s resultants that are resolved tangent-ly onto a given slip plane, which would cause shear, correct? Further, I cant remember if the principal normals sig_xx, sig_yy, sig_zz go to zero when the external loads are resolved onto the slip plane, or just that they do not contribute to plastic deformation?

thank you for your video!

Why we have diagonal matrix sigmakk? There should only be one entry to that matrix at 11 place .

At 22:24, shouldn’t there be T after s(dot)?

At 12:30, I didn’t get the insight why partial sigma(kl)/ partial sigma (ij) is equal to del(il).del(kj).

thank you so much

no body gives the total derivation of consistent tangent modulus Dijkl ep . no clarity.

Tnx , it heped me alot

Hi ! Do you have any video on deriving the stiffness matrix for 4 nodes elements? I mean plane element mass matrix .

Thank you! are there differences between "Shear Locking" and "Mesh Locking"? For what I understand, Mesh locking seems to be the result and "Shear Locking" what in the energetic explaination is the cause. Can you suggest something to deep this topic? Many thanks in advance.

Hi ! Do you have any video on Derivation of stiffness matrices for problems in plane elasticity by the Galerkin method?

Hi! Do you have any video on deriving for a 4 node rectangle stiffness matrix in plane displacement by Galerkin Method?

Hi ! Do you have any video on Derivation of stiffness matrices for problems in plane elasticity by the Galerkin method?

Can you send me your whatsapp number??? I am some queries

Many thanks, it was really helpful

Dear Sir, very nice lectures. I just want to point out one thing you missed (every thing is right, its just that you missed writing a term). Towards the end of the lecture, when you wrote down (ds)^2-(dS)^2 = ..., its just the difference of line segments in current and deformed configurations. The strain would be ((ds)^2-(dS)^2)/(dS)^2) which will come out same as you have written (1/2 (F^T F - I). Thank you, sir.

Yo great vid, you sound like hank hill

excellent video, God bless you

Can you send me your email plz ?

Thank you. Great explanation

By choosing the arbituary basis and weights, what are the most important message and concepts you want to deliver. I believe most of the students will be lost at this point. The message is weak.

Could you make a catalogue? Thank you

Thank you for your time sir, really nice explanation.

very tahnks for this course, please can give us the course for hexaedrique elements 20 nodes?

have you made a video for thin wall polymer cylinders under internal pressure cyclic stress?

Is the test function space V = { v in H1(0,L) such that v(0) = 0}? I'm having trouble interpreting why a(x)u'(x)v(x) at x = 0 goes away.

The vídeo is quite confusing. It'd better to start with small things, such as, how the quadratic form is found, then with the shape functions, finding the vector u. Anyhow, thanks for sharing it.

Poor audio Dislike

why does the partial f partial sigma ij means the nomal to that surface?

Thank you, sir! very clear explanation.

what is delta_ij? and how do I know what that value is?

cant you speak any louder?
