A New ANCF/CRBF Fully Parameterized Plate Finite Element

Journal of Computational and Nonlinear Dynamics, 2016
In this paper, the consistent rotation-based formulation (CRBF) is used to develop a new fully parametrized plate finite element (FE) based on the kinematic description of the absolute nodal coordinate formulation (ANCF). The ANCF/CRBF plate element has a general geometric description which is consistent with the basic principles of continuum mechanics,

Mixed-Coordinate ANCF Rectangular Plate Finite Element

Journal of Computational and Nonlinear Dynamics, 2015
Higher order finite elements (FEs) based on the absolute nodal coordinate formulation (ANCF) may require the use of curvature vectors as nodal coordinates. The curvature vectors, however, can be difficult to define at the reference configuration, making such higher order ANCF FEs less attractive to use.

ANCF curvature continuity: application to soft and fluid materials

Nonlinear Dynamics, 2020
The continuity of the position-vector gradients at the nodal points of a finite element mesh does not always ensure the continuity of the gradients at the element interfaces. Discontinuity of the gradients at the interface not only adversely affects the quality of the simulation results, but can also lead to computer models that do not properly ...

Definition of ANCF Finite Elements

Journal of Computational and Nonlinear Dynamics, 2015
Since the absolute nodal coordinate formulation (ANCF) was introduced, a large number of fully parametrized and gradient deficient finite elements were developed. Some of the finite elements (FE) proposed do not fall into the ANCF category, and for this reason, this technical brief describes the general requirements for ANCF finite elements.

ANCF Consistent Rotation-Based Finite Element Formulation

Journal of Computational and Nonlinear Dynamics, 2015
In this technical brief, a consistent rotation-based formulation is proposed using the absolute nodal coordinate formulation (ANCF) kinematic description. The proposed formulation defines a unique rotation field, employs one interpolation, captures shear deformations, does not suffer from the redundancy problem encountered when using large rotation ...

ANCF reference node for multibody system analysis

Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2014
The objective of this short communication is to introduce the important concept of the absolute nodal coordinate formulation reference node (ANCF-RN), a concept that can be used effectively to develop new and complex multibody system (MBS) models. The ANCF-RN allows for defining constraints and joints using linear algebraic equations, can be used to ...

Use of ANCF Finite Elements in MBS Textile Applications

Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015
The objective of this investigation is to present a new flexible multibody system (MBS) approach for modeling textile roll-drafting sets used in chemical textile industry. The proposed approach can be used in the analysis of textile materials which have un-common material properties best described by specialized continuum mechanics constitutive models,
