Shell buckling lecture 1 by Dr. Ronald Wagner @ Jiangsu University of Science and Technology

[@hnrwagner]

This is my first lecture on shell buckling at the Jiangsu University of Science and Technology, Zhenjiang, China.
It covers buckling in general and cylinder buckling under axial compression. Let me know your thought regarding the content and style of the presentation :)

I found the lecture to be clear and understandable.

Thanks for the lecture,

thanks more is to come :)

Sir please tell me how to do FGM buckling analysis and varying through thickness and I am doing it by referring your videos but it is not validating from the papers and is it necessary to add density??

[@hnrwagner]

here is a FGM example with through thickness analysis, density should be varied if data is present

when in doubt send me paper you want to analyze

[@Pk01121992]

how to model variable-stiffness composite cylinders?

[@hnrwagner]

Working on it, its not as easy as I thought

Many thanks, Dr. Ing. Ronald Wagner. This is a very nice lecture. I hope to see your next lecture.

[@ميكانيك-ف5ت]

Thank you very much, that brings together several cases of buckling

[@hitman5601]

Sir can you please tell me the exact difference between shell model and solid model
And if we do simulation on shell body instead of solid body will there be any difference in results??

[@hnrwagner]

Dont know all the differences, those you have to research yourself, but yeah, there are significant differences for modeling shells with either 2d shell elements or 3d solid elements, in my experience 2d shell elements are better in most cases even for shells with r/t ~10

[@hitman5601]

@@hnrwagner sir whether there will be change in results or it will remain same if we perform analysis on shell model instead of solid model?

Awesome lecture. Much to learn :)
