Experimental Validation of Two Damping Force Models for the ANCF

Volume 5: 6th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2007
Many researchers have studied computer-aided simulations of elastic bodies undergoing large deflections and large deformations. But there have been few attempts to validate the numerical formulations used in these studies. The main aim of this paper is to validate the absolute nodal coordinate formulation (ANCF) by comparing the results to experimental

ANCF analysis of the crude oil sloshing in railroad vehicle systems

Journal of Sound and Vibration, 2018
Abstract With the increase in crude oil rail transportation, accurate modelling of non-Newtonian crude oil rheological properties and the corresponding nonlinear sloshing effects becomes necessary in order to establish safety and operation guidelines.

Analysis of warping deformation modes using higher order ANCF beam element

Journal of Sound and Vibration, 2016
Abstract Most classical beam theories assume that the beam cross section remains a rigid surface under an arbitrary loading condition. However, in the absolute nodal coordinate formulation (ANCF) continuum-based beams, this assumption can be relaxed allowing for capturing deformation modes that couple the cross-section deformation and beam bending,

A Total Lagrangian ANCF Liquid Sloshing Approach for Multibody System Applications

Volume 6: 11th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, 2015
The objective of this investigation is to develop a total Lagrangian non-incremental liquid sloshing solution procedure based on the finite element (FE) absolute nodal coordinate formulation (ANCF). The proposed liquid sloshing modeling approach can be used to avoid the difficulties of integrating most of fluid dynamics formulations, which are based on

ANCF Tire Assembly Model for Multibody System Applications

Journal of Computational and Nonlinear Dynamics, 2015
The aim of this paper is to propose a new numerical approach for modeling tires in multibody system (MBS) applications. In this approach, the tires, including the rigid rim, are modeled using one mesh developed using the finite element (FE) absolute nodal co-ordinate formulation (ANCF).

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

Aniotensin-Converting Enzyme (ACE) Activity: Aortic ancf Endocardial Endothelium Compared

Endothelium, 1996
Vascular endothelial cells release bradykinin (BK), which acts in an autocrine manner to raise intracellular calcium concentrations ([Ca2+]i) and release NO, effects which can be modified by angiotensin-converting enzyme (ACE) inhibitors. Little is known of the effects of BK and ACE inhibitors on endocardial endothelium however.

The Simplest 3- and 4-Noded Fully-Parameterized ANCF Plate Elements

Volume 6: 1st Biennial International Conference on Dynamics for Design; 14th International Conference on Advanced Vehicle Technologies, 2012
In this research, the simplest kinematical models of triangular and rectangular plate finite elements using the absolute nodal coordinate formulation (ANCF) are presented. The ANCF is the finite-element large-displacement-and-rotation approach, which uses the inertial-frame nodal position vectors and their derivatives (slopes) only, without employing ...
