Thanks for the insight rb1957.
Yes, I am using CQUAD4 elements to simulate the structure.
I am already taking into account large displacements and follower forces but, as I said, I cannot reach convergence in SOL 106.
I will take a further look at Timoshenko..didn't know he was irish though ;-)
Hello everybody,
I have a circular plate structure subjected to a uniform pressure load. The plate can be regarded as a membrane and it is clamped around the circumference (the first "circle" of nodes has all 6 DoFs constrained).
I ran a linear analysis and I got high displacements in...
Thank you for your insight, Brian.
I see it. I am carring out a linear static analysis, I haven't investigated the vibration behaviour of the structure yet. I will try to make some checks in this direction.
Ps: I have re-run the analysis with another version of the software: the results are the...
Thank you rb1957 and SWComposites for your replies.
You are both rigth and I also reached your conclusions time ago.
The difference is not so relevant and the model with the RBE2 does not better simulate the reality of the problem.
I was just asking myself why Nastran gives me such results and...
Hello everybody.
I have a shell FE model of a structure that it is made up of a truncated cone shape (just for the sake of clarity, imagine an ice-cream cone without the tip) and a bottom cap (which has a different taper angle, as it would belong to a bigger ice-cream cone) and I am...
