RISEditorial
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the past 5 years, I had the honor to serve as the EditorinChief of the ASME Journal of Computational and Nonlinear Dynamics. This journal was established and sponsored by the ASME Design Engineering Division (DED) ...
Curvature Singularity of Space Curves and Its Relationship to Computational Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Curve geometry plays a fundamental role in many aspects of analytical and computational mechanics, particularly in developing new data-driven science (DDS) approaches. Furthermore, curvature and torsion of space curves ...
Alternate Forms to Lagrange–D'Alembert Principle for Treatment of Rheonomic Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Lagrange–D'Alembert principle is based on the concept of the nonactual and nonmeasurable virtual displacement and the assumption that the system-constraint forces are workless. Because time is not considered in defining ...
Definition of ANCF Finite Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
ANCF Tire Assembly Model for Multibody System Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
ANCF Consistent Rotation Based Finite Element Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this technical brief, a consistent rotationbased formulation is proposed using the absolute nodal coordinate formulation (ANCF) kinematic description. The proposed formulation defines a unique rotation field, employs ...

Convergence Characteristics of Geometrically Accurate Spatial Finite Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The convergence characteristics of three geometrically accurate spatial finite elements (FEs) are examined in this study using an eigenvalue analysis. The spatial beam, plate, and solid elements considered in this investigation ...
Kinetic- and Strain-Energy Approaches in the Thermal Analysis of Constrained Mechanical Systems: A Comparative Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Despite the unconstrained thermal expansion is assumed stress-free, the conventional FE approach requires formulating elastic forces, and this in turn leads to elastic stresses. A displacement-based formulation, on the ...
Mixed Coordinate ANCF Rectangular Plate Finite Element
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
