will you continue making videos??? can you please post the study materials you referred to while making this video?

@solidmechanicsclassroom3224 3 жыл бұрын

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

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! :-)

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

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?

@solidmechanicsclassroom3224 2 жыл бұрын

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

Structural dynamics is also represented by a partial differential equation. So FEM is used to solve the governing equation, to obtain the dynamic response.

So when we changes the loading ratios like R =0.1, R=0.25 etc then how it will affect the striations?
