This paper presents the theory for the Lagrange co-rotational (CR) formulation of finite elements in the geometrically nonlinear analysis of 3D structures. In this paper, strains are assumed to be small while the magnitude of rotations from the reference configuration is not restricted. A new best fit rotator and consistent spin filter is derived.

Hello Likask
Hi Likask
As a part of my PhD, I need to implement a slender beam dynamic in 3D with displacement control
Have you ever implementes a code usid 3d corotational beam element
I will be very gartefull to see you algorithm if you managed to del with large rotations in 3D beams.
Best Regards
