In this tutorial we examine the bucking analysis of cylinders, which first requires a linear buckling analysis and superposition of imperfections on the modeshapes scaled up to measured or expected shell imperfections.

Great video. This video is very useful.
Thank you.

[@SalahM07]

Very good explantation thanks

[@josephwoltering3785]

Great video, thank you.

[@VinayGoyal]

your welcome

[@dadamine3263]

Thanks Sir

[@eltugaball1571]

Hey. Great video. I was only left wondering what what happen if you hadn't included the imperfections. Could convergence still be reached?

useful video,
if we want to make a static, general after riks step, how can we do it in abaqus?

[@debbygu3074]

Hello, Vinay, Can you tell me what is the difference between "Dependence" and "Independence" during setting Assembly?

[@CuongNguyen-tt4jp]

If we have a job with 2 steps, the first step is static, general and the second one is static, Riks. so how can we apply the imperfection for only the second job?
wish your helping!

[@theerthaps7525]

Sir, how can we introduce residual stress to a model

The use of second order element will change the results. Which one is better?

[@VinayGoyal]

Second order elements

[@chipchipchinese2716]

hi, pls let me known buckling load the bigger the better or the smaller the better. thanks

[@VinayGoyal]

Higher is better

[@georgehalamandaris612]

It is helpful to visualize your imperfection by scaling the mode by .5 or 1 and run the nonlinear run for a few steps and check results, this will make it easier to visualize one's mode combination:
e.g.
*IMPERFECTION, FILE=filename, STEP=1
1, 1
2, 1
3, 1

[@juancervi1834]

inkeywords, you shall put *NODE FILE, instead of *NODE FIL

[@VinayGoyal]

Both work
