I tried again with your advice and entered the *Node File keyword in the buckling analysis after *Output requests. The riks simulation WORKED! I introduced the imperfections from buckling mode 7 and stretching the system 50%. I could compare it to the results from introducing no imperfections...
That's wonderful! Many times researchers don't share their simulation parameters, it's great to see they did.
I think we are getting closer from getting some interesting results. I am following the manual about how to introduce imperfections...
I tried lowering the shell thickness, changing the young's modulus and increasing the strain level but there is still no out-of-plane deformation.
It seems there is something else missing in the simulation parameters. Thanks for your support so far, I appreciate it a lot
Thank you so much for your prompt reply! Nlgeom was not turned on, but I tried again turning it on (under "Steps" section), unfortunately with very similar results (actually slightly worse, 107MPa instead of 105MPa of maximum stress).
PS: I have the 2017 version, maybe that's why .CAE can't...
Hello!
I have a relatively simple engineering case that I hope you can help me with. I am trying to simulate the behavior of a flat "S shape" structure under deformation (50% strain). What I am expecting from designing such "S shape" structure is a release of strain by unfolding on the Z...
