thank you so much. can you please give me your what's app number? or email? I want to discuss something with you. I sent you email on the address given in the video. but it was bounced back
Hi. if we want to add imperfections on which step on the timecode we can insert that. if possible please make a video on that too. and also in BC and loading section I haven't seen where you put the loading force.
Sir, where can I get the data of axial force to axial displacement of experimental? I want to practice making graphs use excel just like the video. Your serials of abaqus tutorial are very helpful. Thank you very much .
@@hnrwagner In this report，the predicted buckling loads and measured buckling loads agreed within 1%, so why NASA concerned about the knockdown factors?
@@zhiminghe6310 @Zhiming He a KDF is always required for certification plus an additional safety factor. The official KDF for this shell would be 0.60 according to the NASA SP-8007. The KDF with respect to the exp. test is 0.87. The KDF according to new design methods would be for this shell 0.68.
just watched the entire video and added timecodes for better overview. What is too fast for you? I think it is appropriate, it is not for beginners for sure.
What kind of shell buckling analysis do you want to see next ? comment below !
Finite elastoplasticity shell (isotropic / orthotropic)!
Can you consider the effects of the stiffened cylinders on their strength? It í very interesting.

I do not understand the question ? could you rephrase it and give an example.

Sir, is modelling of ETTA1similar to this

I make a new video soon with imperfections.

Dear sir,
how can we get thickness distribution in metal forming in abaqus
Can you give a reference? Dont know what you mean
what happened to you? why are you so fast. please repeat the steps slowly. very difficult to follow you
