will you continue making videos??? can you please post the study materials you referred to while making this video?
I wish to make videos but I can't do it very regularly, What are some of the topics you might be interested in ?
The content in this video is a result of many ideas that were integrated over a decade of time from my academic and industry experience, and some critical thinking. I haven't referred to any particular study material.
If you are a beginner refer Seshu, if you are intermediate, refer the book by Robert Cook
@@solidmechanicsclassroom3224 it is the best introduction to FEM I've seen so far. Thx
@@solidmechanicsclassroom3224 please continue in FEM
This is a very good overview of FEM, without even delving into the needed Rooms, Theorems and Definitions.
I have never seen a better explanation of FEM. This video anwered a lot of my lingering questions. You are truly an outstanding teacher.
It is called weak form because it weakens the conditions in weighted residue statement.
One no longer need satisfy double differential of solution but only single differential of solution.
the most simple explanation of a complex procedure I have ever hear in my life.. Thank you sir
Yes, that's correct. It weakens the continuity requirements of the solution field.
Please continue this (FEM) series
Don't stop making videos on solid mechanics. So helpful they are!!!
Thank you! I like that you talk about the mathematical process and give a clear explanation.
This may just be the best video i’ve ever watched for explaining a topic. I’ve been completely lost since my prof started this section and everything is making so much sense thank you for explaining so well
@Isabellaa 1234 ,can you help me please,I have question
Beautiful explanation… it’s my first encounter with FEM and I’m hooked
This is a wonderful video. Thanks!!! I loved your explanation. Can you also explain the other parts of FEM? Also, it would be great if you explain what happens in the FEM softwares like ABAQUS or ANSYS. Students try to use the software without having the knowledge of which element to be chosen under which conditions and what assumptions are made while selecting the element type. If someone explains like you, it would be very easy for students to understand. Thanks in advance! :-)
Absolutely beautiful presentation giving a clear picture of FEM . so nice to watch it. Mashallah
Very well explained for layman
Thank you for your precise explanation sir..🙂🙂 Now i got an over view of FEM..🙃
Thank you sir for the simplest explaination
10:10 Usally we called FEM as - Finite Elements Method .But I'm calling as " it's Not FINE Elements Method " to understand .
Thanks for sharing your knowledge! Gyan baatne se badhta hai.
Absolutely beautiful presentation giving a clear picture of FEM . so nice to watch it.
Bro this is best video I have ever seen on FEA
Dear Sir,
Glad you are back after long time. Hope you are safe and healthy.
I very much request you to make a video on elastic shakedown , plastic shakedown, and ratcheting.
Please respond if you read my comment.
Punit- Thanks!
I will put this on my list but as I am a working professional, this may not be out soon.
@@solidmechanicsclassroom3224
I understand.
Thank you. Sir.
Please continue your good work
Great explanation.
From slide 7 to slide 8 phi turned into f.
Once again you came up with an intuitive explanation.. Nice work Dr. Prithvi..
This is one of the best introductory videos to FEM. Great job!
Fantastic video sir thanks for your good explanation
What a overview! Amazed by mathematical explanation, please explain difference and choice between FDM, FEM, FVM, etc.
I have question can you help me please
Wow mind blowing explanation.
Wonderful explanation - short and sweet
Very flavoured explanation. Excellent job.
Amazing explanation for layman
Nice over view
Thank you very much
Thanku very much sir. Very easy to understand.
Amazing explanation
Excilent sir ji
Absolutely loved this video. What an elegant explanation that is incredibly easy to follow.
Best video on fem .
Great one! Want a vedio on nonlinear fem
good explanation many thanks
Wow! Great demonstration..
nice to see u again sir ,please make more videos
Wow. FEM in 11 minutes!!
Ohhhhh my god...you are just next level
Very insightful and wise. Thanks
Excellent video. thankyou!.
Well described, well organized, just super... Very nice job!
Very concise and informative, thank you so much ❤
Great video.! Thank you!
Awesome sir. Thank you.
Good explanation. Thank you sir.
Very well explained sir.
Great sir please upload more videos we are waiting
Good!!!
Very clear, thanks a lot!
Sir, the volume of audio is very low in almost all of your videos, please raise it little.
Very well explained.
amazing video
Would you recommend a student to work with software like ansys directly after taking the undergraduate courses in fluid mechanics, solid mechanics etc?
Or should he take courses on fem, cfd and write his own codes before using such softwares?
Is there any harm in directly using a canned software like ansys?
would definitely recommend understanding the concepts of FEM (say, the basic machinery) before using a commercial software (say, black box) like Ansys. Additional reading : www.quora.com/How-do-I-apply-theoretical-knowledge-of-FEM-in-ansys/answer/Prithivirajan-Veerappan
@@solidmechanicsclassroom3224 i need your email please
No I think that anyone who wants to understand the basic concepts of FEM or CFD he must at least at the beging write his own codes, not to very hard problems but hard enough thus he will understand the basic concepts. Then he can use his knowledge to understand how software's like ANSYS uses this concepts, so in this way anyone can be sure that he will use the right parameters like type of elements boundary conditions etc, at his modeling
wonderful video, thank you
Nice 👍

What is the use of fem in dynamics and earthquake engineering
Structural dynamics is also represented by a partial differential equation. So FEM is used to solve the governing equation, to obtain the dynamic response.
sir, can you explain how did the first term in the weak form occur after the integration by parts?
We need to use the integration by parts for higher dimensions, involves Green's identities. Please look up.
@@solidmechanicsclassroom3224 thanks a lot
Cool
Thank you sir
thanks for video.
Well done!
Thank you for the video! Would you recommend a programming software that is FEM friendly?
You could use either Matlab or Python
@@solidmechanicsclassroom3224 Thank you! In matlab I see the PDE tool supports the boundary condition with only either Dirichlet or Neumann, I have a problem that is neither of them, would there be some packages on Matlab that support more general conditions?
very nice
thank you!
great job !!! :)
Thank u
Sir,
Can you give some insights on striations and load applied on specimen?
Could you expand on your question in detail ? Striations in context of what ?
@@solidmechanicsclassroom3224
Sir,
I am working on fatigue failure. So when crack increase say from some X mm to Z mm then it left striations marks on surface which we can see in FESEM images.
So when we changes the loading ratios like R =0.1, R=0.25 etc then how it will affect the striations?
I am electronics engineer, doing Ph.D. in the field of signal processing of Acoustic emission NDT.
@@deepakjoshi4643 This is a research question and I may not be able to help you with that. If you have fundamental questions on solid mechanics, I could possibly help. Thanks.

Ok Sir,
Thank You.

what is the meaning of max stress on the fixed boundary (compare the max stress on structure)in FEM simulation?
I´m an argentinian student i need subtitles please
But still jobs in this domain are very limited & mostly hired only IITians or foreign MS employees.
Can someone try to explain how the integration by parts thing works? Thanks! I'm also starting FEM this semester and I already know its gonna be a ballbuster. This video gave me a little leap ahead :)
What happened bro with your Experience with FEM?
@@mechartisan6813 got a C somehow…however during the spring semester my university used the pass/fail system so it turned into an S (satisfactory)
bruh I like it can you explain FVM
CAn i have your slides if you can
Difficult to understand for beginners
It's Quite easy 😅😅
I watch the video but have no idea what is u, u with a hat, their second derivate and omage in the equations, so the whole matematical treatment makes no sense for me.
Thanks
But it's hard to understand indian accent

Hi
@@fea_dme_creo_hypermesh hi . Is FEM subject very difficult?
You have to improve your English, a lot!
nice.. thank you
