Vibration of plane trusses by the Newmark method
Computers & Structures, 1990Abstract The determination of the vibration of a plane truss by the Newmark numerical method is presented. This method is an alternative approach based on manual computation for design use, which is a classical discrete method using elastic weights and a tabular procedure.

Stability properties of the newmark, Houbolt and Wilson theta methods
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1980AbstractThis paper analysis the stability of several methods for obtaining numerical solutions of second‐order ordinary differential equations. The methods are popular in structural and geotechnical engineering applications and are direct, that is they do not require the transformation of the second‐order equation into a first‐order system.

A simplified method for estimating Newmark displacements of mountain reservoirs [PDF]
Soil Dynamics and Earthquake Engineering, 2017 In the present article we propose a new simplified method for assessing the seismic performance of large mountain reservoirs. The pseudo-empirical regression model is established on the basis of decoupled dynamic analyses performed on 7 accelerograms applied to 33 structural and geotechnical configurations.

A STOCHASTIC NEWMARK METHOD FOR ENGINEERING DYNAMICAL SYSTEMS
Journal of Sound and Vibration, 2002Abstract The purpose of this study is to develop a stochastic Newmark integration principle based on an implicit stochastic Taylor (Ito–Taylor or Stratonovich–Taylor) expansion of the vector field. As in the deterministic case, implicitness in stochastic Taylor expansions for the displacement and velocity vectors is achieved by introducing a couple ...

An Uncoupling Strategy in the Newmark Method for Dynamic Problems
2017When the semidiscrete formulation of the finite element method (FEM) is employed in traditional elastodynamic problems, a system of ordinary differential equations (ODEs) is obtained. The present paper focuses on the development of a numerical strategy to decouple the resulting system by means of the implicit unconditionally stable Newmark method ...

The Newmark Method and a Moving Inertial Load
2012The Newmark method (see Section 5.5) is considered here as a representative example of a wide family of time integration methods. It is attractive since most of computational procedures in structural dynamics are based on this numerical scheme.

Newmark’s Time Integration Method From the Discretization of Extended Functionals
Journal of Applied Mechanics, 2005Abstract In this note we illustrate how to obtain the full family of Newmark’s time integration algorithms within a rigorous variational framework, i.e., by discretizing suitably defined extended functionals, rather than by starting from a weak form (for instance, of the Galerkin type), as done in the past.

Solving constrained mechanical systems by the family of Newmark and α‐methods
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2006AbstractThe family of Newmark and generalized α‐methods is extended to constrained mechanical systems by using simultaneous position and velocity stabilization as key ideas. In this way, the acceleration constraints need not be evaluated, and the overall algorithm is about as expensive as the application of a BDF method to the GGL‐stabilized equations ...
