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 ...

Rational ANCF Thin Plate Finite Element

Journal of Computational and Nonlinear Dynamics, 2016
In this paper, a rational absolute nodal coordinate formulation (RANCF) thin plate element is developed and its use in the analysis of curved geometry is demonstrated. RANCF finite elements are the rational counterpart of the nonrational absolute nodal coordinate formulation (ANCF) finite elements which employ rational polynomials as basis or blending ...

Elastodynamics of the Rigid-Flexible 3-ṞRR Mechanism Using ANCF Method

Lecture Notes in Computer Science, 2014
The elastodynamics of the 3-RRR mechanism is studied in this paper. The absolute nodal coordinate formulation (ANCF) is used to model the flexible links, the generalized α method with several efficient methods are adopted to solve the equations of motion of the system. A comparison is made between the rigid and flexible links of the mechanism.

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.

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,

ANCF Modeling of the Contact Geometry and Deformation in Biomechanics Applications

Volume 2: 32nd Computers and Information in Engineering Conference, Parts A and B, 2012
The purpose of this investigation is to demonstrate the use of the finite element (FE) absolute nodal coordinate formulation (ANCF) and multibody system (MBS) algorithms in modeling both the contact geometry and ligaments deformations in biomechanics applications. Two ANCF approaches can be used to model the rigid contact surface geometry. In the first
