ANCF Multiplicative-Decomposition Thermoelastic Approach for Arbitrary Geometry

Journal of Structural Engineering, 2021
AbstractThe classical approach for the thermal analysis of solids and fluids uses the strain additive decomposition to account for the effect of the temperature.

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 ...

ANCF Analysis of Textile Systems

Journal of Computational and Nonlinear Dynamics, 2015
This paper presents a new flexible multibody system (MBS) approach for modeling textile systems including roll-drafting sets used in chemical textile machinery. The proposed approach can be used in the analysis of textile materials such as lubricated polyester filament bundles (PFBs), which have uncommon material properties best described by ...

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 ...
