Frequency analysis with beam and solid elements
Frequency analysis with beam and solid elements
(OP)
Hi,
I have carried out a frequency analysis of a simply supported beam by comparing the results between beam and solid elements. The beam elements match the solutions with my hand calculations. However, solid elements do not give very close solutions. Does anyone knows what the problem is with solid elements?
Thanks a lot.

And if this is a simple supported structure and your model is good, the solid elements should give a more precise answer.
But, as mentioned, if the beams are slender, difference should be small.
For thick beams, eg. check with roark formulas for stress and strain.
