A high-precision co-rotational formulation of 3D beam elements for dynamic analysis of flexible multibody systems

Evaluating inertia forces is a central and complicated task for dynamic analysis of flexible multibody systems (FMS) involving large displacements and rotations. In a number of co-rotational approaches, cubic interpolations are adopted to formulate both inertia and internal forces, where the inertia...
