modeling of a Euler Bernoulli beam with solid elements
modeling of a Euler Bernoulli beam with solid elements
(OP)
Hi Experts
I'm modeling a simply-supported beam structure and computing natural frequency. I got natural frequencies of the beam similar to analytic solutions using wire-beam element. However, I don't know how I can model it with solid elements. The assumption for Euler-Bernoulli beam is the section should remain plane after deformation and normal to the deformed axis of a beam. In the wire-beam case, I don't the beam section is always located at the normal to thehttp://www.eng-tips.com/threadminder.cfm?pid=799# "wire" but, I don't know how to set it up with the solid element.
If you know answer, please give me comments.
Thanks

RE: modeling of a Euler Bernoulli beam with solid elements
So actually I don't understand your problem.

I'd imagine it would be a nightmare to specify plane sections remain throughout the beam and whatever other assumptions there are.
RE: modeling of a Euler Bernoulli beam with solid elements
I know several people already have worked on this topic but, I want to compare FEM results with theoretical equations (closed form solutions)
However, the existing theoretical solutions are based on the assumption of Euler-Bernoulli.
Unfortunately, I don't know how to model moving mass and oscillator on the wire beam in ABAQUS, but I can do this on the solid beam.
That's why I am trying to find a way to make them the Euler-Bernoulii condition.
Does anyone help?

Is there a reason you can't just put these on the beam central nodes?

If you know how to model it, could you give me some ideas? I think moving load is not difficult but, how can I move mass on a wire beam?
Please help...
