Buckling analysis of beam structure with absolute nodal coordinate formulation

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2020
Absolute nodal coordinate formulation (ANCF) was applied to the buckling analysis. A delicate analysis scheme based on dichotomy method was proposed to solve the buckling problem with beam elements whose tangent stiffness matrix is a highly nonlinear function of nodal coordinates. Three existing planar beam elements are employed to show the application.

A New Plate Element Based on the Absolute Nodal Coordinate Formulation

Volume 6A: 18th Biennial Conference on Mechanical Vibration and Noise, 2001
Abstract In this investigation, a method for the finite rotation and large deformation analysis of plates is presented. The method, which is based on the absolute nodal coordinate formulation, leads to a plate element capable of representing exact rigid body motion.

Efficiency of non-dimensional analysis for absolute nodal coordinate formulation

Nonlinear Dynamics, 2016
Absolute nodal coordinate formulation was developed in the mid-1990s. The adoption of the continuum mechanics concept has allowed large displacements and large deformations to be expressed in flexible body analysis. However, the analysis time increases due to the increased number of degrees of freedom at nodal points.

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.

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.

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 ...
