Dear Professors,
I am recently studying beam element to employ it, and I found the element framf3e in FEAP, and I am curious that if there is a reference paper about it like other element, I found a paper written by Simo, Tarnow, and Doblare, which named "Non-linear dynamics of three-dimensional rods : Exact energy and momentum conserving algorithms", I do not konw if it is correct, since the last modification record said that "! Modified to standard FEAP element ! R. Taylor - January 1997", I am a little confused. Can you spare some time to have a look, thanks.
Best wishes
Huxiang Shi
