thank you for the example! it is nice to know how to get the stiffness simply from the modal but I think for a fairer comparison we should have calculated the stiffness analytically as well!
I have a question, when studying rotor dynamic, we plot campbell diagram. I always see the curves going linear and symmetric, but what happen when the curves aren't linear and symmetric? I'm dealing with a project and I can't explain why one of the curves isn't linear.
How can I model a concrete filled steel tube with binding bar, Please? Which type of element or sections can I use to model the tie bar, truss or beam section? If I use a truss section, How can I model the connection between the tie bar and the steel tube which is shell element? How will the connection be if I want it to be a hinge connection? Can you explain the constrain types, please? and finally can you make a video to explain the STATIC RIKS steep like that you made for Dynamic Explicit, please? Thank you very much
hi sir. i want to calculate natural frequency of plate in contact with moving fluid on one side. is that possible with Abaqus? have you any idea for this case sir?
How to deal it with if we use top diameter instead of angle and different thickness at bottom and top

Thank you very much for the video. Please is there a way to reduce the natural frequency of the system
very useful information. thank for sharing
