RISOn an Improved Time Integration Scheme for Stiff Constitutive Models of Inelastic Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For the time-integration of stiff constitutive models of inelastic deformation, the explicit (one step Euler) integration scheme can be used provided the time step size is closely monitored and ...
Coupling of Extension and Twist in Single-Walled Carbon Nanotubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a study of the deformation behavior of single-walled carbon nanotubes (SWNTs) subjected to extension and twist. The interatomic force description is provided by the Tersoff-Brenner ...
Fully Lagrangian Modeling of Dynamics of MEMS With Thin Beams—Part I: Undamped Vibrations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micro-electro-mechanical systems (MEMSs) often use beam or plate shaped conductors that can be very thin—with h/L≈O(10–2–10–3) (in terms of the thickness h and length L of the beam or side of ...
Fully Lagrangian Modeling of Dynamics of MEMS With Thin Beams—Part II: Damped Vibrations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micro-electro-mechanical systems (MEMS) often use beam or plate shaped conductors that are very thin with h/L≈O(10−2–10−3) (in terms of the thickness h and length L of a beam or side of a ...
A Geometrically Exact Rod Model Including In-Plane Cross-Sectional Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a novel approach for nonlinear, three dimensional deformation of a rod that allows in-plane cross-sectional deformation. The approach is based on the concept of multiplicative ...
Nonlinear Vibrations of Viscoelastic Composite Cylindrical Panels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is devoted to mathematical models of problems of nonlinear vibrations of viscoelastic, orthotropic, and isotropic cylindrical panels. The models are based on Kirchhoff-Love hypothesis ...
Numerical Integration of Some Stiff Constitutive Models of Inelastic Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several strategies for numerical time-integration of some stiff constitutive models of inelastic deformation are presented in this paper. Numerical results and comparisons are presented for the ...
A Finite Element Analysis of Single-Walled Carbon Nanotube Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: (2009, “An Atomistic-Continuum Cosserat Rod Model of Carbon Nanotubes,” J. Mech. Phys. Solids, 57, pp. 932–958), in a 2009 JMPS paper, proposed an atomistic-continuum model, based on Cosserat ...
Nonlinear Vibrations of Beams, Strings, Plates, and Membranes Without Initial Tension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The subject of this paper is nonlinear vibrations of beams, strings (defined as beams with very thin uniform cross sections), plates and membranes (defined as very thin plates) without initial ...
The Role of Beam Flexibility and Ground Contact Model in the Clattering of Deformable Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been shown in previous research that, relative to (the usually considered case of) a single impact, multiple impacts (clattering) of rigid casings can greatly enhance the probability of ...
