Validation of Flexible Multibody Dynamics Beam Formulations Using Benchmark Problems [PDF]

, 2014
As the need to model flexibility arose in multibody dynamics, the floating frame of reference formulation was developed. Unfortunately, this approach can yield inaccurate results when elastic displacements becomes large.
