thread378-292471: Pipe finite element

Hello All, does anyone know of an applicable element 1-Dimensional element that adheres to the Winkler-Bach theory?

I've looked through a great deal of technical papers, books, forum topics, and even performed several tests with different hand-written and pre-processed decks to test the capabilities of the CBEAM and CBEND elements with no avail. The models just don't correlate to analytical examples with regards to stress. There's commonly greater than 10 percent error. So I've come here to ask if anyone knew of NASTRAN-style 1D elements that were closer to Winkler-Bach than Timoshenko or Euler-Bernoulli. Topic is related in that a tubing finite element would probably also work but the NASTRAN CBEND element was not sufficient (Maximum fiber stresses weren't even asymmetric, go figure).

Thanks.
