Coordinate Mappings for Rigid Body Motions
(The American Society of Mechanical Engineers (ASME), 2017)Geometric methods have become increasingly accepted in computational multibody system (MBS) dynamics. This includes the kinematic and dynamic modeling as well as the time integration of the equations of motion. In particular, ... -
Compound Synchronization Based on Memristive Cellular Neural Network of Chaos System
(The American Society of Mechanical Engineers (ASME), 2017)As a especial type of synchronous method, compound synchronization is designed by multiple drive systems and response systems. In this paper, a new type of compound synchronization of three drive systems and two response ... -
Nonlinear Dynamic Response of Carbon Nanotube Nanocomposite Microbeams
(The American Society of Mechanical Engineers (ASME), 2017)The nonlinear dynamic response of nanocomposite microcantilevers is investigated. The microbeams are made of a polymeric hosting matrix (e.g., epoxy, polyether ether ketone (PEEK), and polycarbonate) reinforced by ... -
Numerical Determination of Pseudobreathers of a Three-Dimensional Spherically Symmetric Wave Equation
(The American Society of Mechanical Engineers (ASME), 2017)A numerical method for finding spherically symmetric pseudobreathers of a nonlinear wave equation is presented. The algorithm, based on pseudospectral methods, is applied to find quasi-periodic solutions with force terms ... -
Extensional Response and Equilibrium Kinetics of Torsionally Relaxed dsDNA Under Tension: A Brownian Dynamics Study
(The American Society of Mechanical Engineers (ASME), 2017)Deoxyribonucleic acid (DNA) is a long flexible polyelectrolyte that is housed in the aqueous environment within the cell of an organism. When a length of torsionally relaxed (untwisted) DNA is held in tension, such as is ... -
A New ANCF/CRBF Fully Parameterized Plate Finite Element

Traveling Wave Solutions of a Two-Component Dullin–Gottwald–Holm System
(The American Society of Mechanical Engineers (ASME), 2017)In this paper, we investigate the traveling wave solutions of a two-component Dullin–Gottwald–Holm (DGH) system. By qualitative analysis methods of planar systems, we investigate completely the topological behavior of the ... -
A Geometrically Exact Contact Model for Polytopes in Multirigid-Body Simulation
(The American Society of Mechanical Engineers (ASME), 2017)We present a formulation of nonpenetration constraint between pairs of polytopes which accounts for all possible combinations of active contact between geometric features. This is the first formulation that exactly models ... -
Integrability of Velocity Constraints Modeling Vortex Shedding in Ideal Fluids
(The American Society of Mechanical Engineers (ASME), 2017)A mathematical model that invokes the Kutta condition to account for vortex shedding from the trailing edge of a free hydrofoil in a planar ideal fluid is compared with a canonical model for the dynamics of a terrestrial ... -
Implementation Details of a Generalized-α Differential-Algebraic Equation Lie Group Method
(The American Society of Mechanical Engineers (ASME), 2017)Configuration spaces with Lie group structure display kinematical nonlinearities of mechanical systems. In Lie group time integration, this nonlinear structure is also considered at the time-discrete level using nonlinear ... -
Identification of a Subsystem Located in The Complex Dynamical Systems Subjected to Random Loads
