Reduction of degrees of Freedom in three-dimensional ANCF beam of 24-DOF beam element by component mode synthesis

open access: yesNihon Kikai Gakkai ronbunshu, 2014
This paper describes how to reduce degrees of freedom for the absolute nodal coordinate formulation (ANCF) of three-dimensional beam made up of 24 degrees of freedom beam elements by applying the component mode synthesis. The stiffness matrix of the ANCF

Parameter estimation for the Euler-Bernoulli-beam [PDF]

open access: yes
An approximation involving cubic spline functions for parameter estimation problems in the Euler-Bernoulli-beam equation (phrased as an optimization problem with respect to the parameters) is described and convergence is proved.

Nano and viscoelastic Beck's column on elastic foundation

open access: yes, 2014
Beck's type column on Winkler type foundation is the subject of the present analysis. Instead of the Bernoulli-Euler model describing the rod, two generalized models will be adopted: Eringen non-local model corresponding to nano-rods and viscoelastic ...

Wearable Metamaterials with Embodied Intelligence for Programmable Control of Human Limbs Tremor

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Resulting from alternating muscle contractions, tremors can severely limit human ability to perform everyday tasks like walking or talking, due to their disruptive nature. Medication and surgery may not always effectively address tremor control. A wearable device embodying programmable smart metamaterials with adaptable intelligence to meet the demand ...

Random Vibration of Space Shuttle Weather Protection Systems

open access: yesShock and Vibration, 1995
The article deals with random vibrations of the space shuttle weather protection systems. The excitation model represents a fit to the measured experimental data. The cross-spectral density is given as a convex combination of three exponential functions.

Tension-induced non-linearities of flexural modes in nanomechanical resonators

open access: yes, 2013
We consider the tension-induced non-linearities of mechanical resonators, and derive the Hamiltonian of the flexural modes up to the fourth order in the position operators. This tension can be controlled by a nearby gate voltage.

Dynamic boundary control of a Euler-Bernoulli beam [PDF]

open access: yesIEEE Transactions on Automatic Control, 1992
A flexible beam, clamped to a rigid base at one end and free at the other end is considered. To stabilize the beam vibrations, a dynamic boundary force control and a dynamic boundary torque control applied at the free end of the beam are proposed. It is proved that with the proposed controls, the beam vibrations decay exponentially.

The Shear Effect of Large-Diameter Piles under Different Lateral Loading Levels: The Transfer Matrix Method

open access: yesBuildings
In various analytical models, modeling the behavior of large-diameter monopiles and piles can be challenging due to these foundations with huge body sizes carrying mechanisms of lateral loads to the surrounding soils.
