A New Algorithm for the Evaluation of the Elastic Forces in the Absolute Nodal Coordinate Formulation
(Eccomas Proceedia, 2004)
The use of the Absolute Nodal Coordinate Formulation (ANCF) to model flexible multibody systems leads to a system of equations in which the mass matrix is constant. Among other advantages of the ANCF, as the simplicity ...

Dynamic simulation of reeving systems with the extension of the modal approach in the axial direction
(American Society of Mechanical Engineers, ASME Digital Collection, 2021)
In this work, the simulation of reeving systems has been studied by including axial modes using the Arbitrary Lagrangian-Eulerian (ALE) description. The reeving system is considered as a deformable multibody system in which ...
