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
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
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! :-)
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.
@@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?
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
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
@@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.
Structural dynamics is also represented by a partial differential equation. So FEM is used to solve the governing equation, to obtain the dynamic response.
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 :)
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.

@@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.
Thank you! I like that you talk about the mathematical process and give a clear explanation.
Don't stop making videos on solid mechanics. So helpful they are!!!
I have never seen a better explanation of FEM. This video anwered a lot of my lingering questions. You are truly an outstanding teacher.
Absolutely beautiful presentation giving a clear picture of FEM . so nice to watch it.
Please continue this (FEM) series
Once again you came up with an intuitive explanation.. Nice work Dr. Prithvi..

It is called weak form because it weakens the conditions in weighted residue statement.

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.

Beautiful explanation… it’s my first encounter with FEM and I’m hooked
Great explanation.
From slide 7 to slide 8 phi turned into f.
Bro this is best video I have ever seen on FEA
Well described, well organized, just super... Very nice job!
Very flavoured explanation. Excellent job.
Wonderful explanation - short and sweet
Ohhhhh my god...you are just next level
Absolutely loved this video. What an elegant explanation that is incredibly easy to follow.
Very insightful and wise. Thanks
Amazing explanation for layman
nice to see u again sir ,please make more videos
Please continue your good work
What a overview! Amazed by mathematical explanation, please explain difference and choice between FDM, FEM, FVM, etc.

Great one! Want a vedio on nonlinear fem
Cool
Wow. FEM in 11 minutes!!
Thank you sir
Thank u
Good!!!
very nice
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

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 ?
