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.
*NODE FILE
U,
Very good explantation thanks
Great video, thank you.
your welcome
Hello, Vinay, Can you tell me what is the difference between "Dependence" and "Independence" during setting Assembly?
Thanks Sir
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?
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!
inkeywords, you shall put *NODE FILE, instead of *NODE FIL
Both work

Sir, how can we introduce residual stress to a model
The use of second order element will change the results. Which one is better?
Second order elements
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
hi, pls let me known buckling load the bigger the better or the smaller the better. thanks
Higher is better
