Comparison of the absolute nodal coordinate and geometrically exact formulations for beams

Multibody System Dynamics, 2013
The modeling of flexibility in multibody systems has received increase scrutiny in recent years. The use of finite element techniques is becoming more prevalent, although the formulation of structural elements must be modified to accommodate the large displacements and rotations that characterize multibody systems.

Computer Implementation of the Absolute Nodal Coordinate Formulation for Flexible Multibody Dynamics

Nonlinear Dynamics, 1998
This paper describes procedures for the computer implementation of the absolute nodal coordinate formulation for flexible multibody applications. In the absolute nodal coordinate formulation, no infinitesimal or finite rotations are used as nodal coordinates.

Deformation modes in the finite element absolute nodal coordinate formulation

Journal of Sound and Vibration, 2006
Abstract The objective of this study is to provide interpretation of the deformation modes in the finite element absolute nodal coordinate formulation using several strain definitions. In this finite element formulation, the nodal coordinates consist of absolute position coordinates and gradients that can be used to define a unique rotation and ...

Studies on the Kinematics of Thin Shell Elements Based on the Absolute Nodal Coordinate Formulation

Volume 6: 10th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2014
The absolute nodal coordinate formulation (ANCF) is a finite element procedure that has been developed specifically for the dynamic analysis of large deformation problems. This study concerns compatibility problems in thin rectangular ANCF shell elements, which have been reported in a recent study revealing that these elements lead to a loss of inter ...

Comparison Between the Absolute Nodal Coordinate Formulation and Incremental Procedures

1999
Abstract : Many flexible multibody applications are characterized by high inertia forces and motion discontinuities. Because of these characteristics, problems can be encountered when large displacement finite element formulations are used in the simulation of flexible multibody systems.

Analysis of Higher and Lower Order Elements for the Absolute Nodal Coordinate Formulation

Volume 6: 5th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2005
A higher order and a reduced order element for the analysis of thin beams using the absolute nodal coordinate formulation are investigated. Additional shape functions are introduced for the existing spatial absolute nodal coordinate beam element in order to increase its accuracy.

Deformation of Thin-Walled Structures in Assemble Process with Absolute Nodal Coordinate Formulation

2015
The assemble precision of thin-walled structures are very important in engineering, which affects the performance of the mechanism. Large rotations are easy to occur in these structures during assembling process due to their geometric features. So it is necessary to establish a precise model of the thin-walled structure to predict its deformation.
