Beam theory usid in Simulate

[peterarras]

hi all,

I'm trying to figure out what beam theory is used in Simulate with beam elements.

Is it Timoshenko's theory is which a section can rotate or is it Eulers-Bernouillis theory in which a cross section is always considered to be perpendicular to the neutral viber?

Unfortunately i cannot trace it in the help-files (is the anwer very well hidden in there?) .

Thanks,

Peter

It's Timoshenko. You can verify this by creating a short beam and doing a comparison analysis between one with a Poisson's Ratio of 0.3 and another with -0.999 (the latter will behave like an Eulers-Bernouillis beam).
