Vibrations of a Timoshenko beam on an inertial foundation under a moving load

MATEC Web of Conferences, 2018
In the paper vibrations of the Timoshenko beam on an inertial foundation subjected to a moving force are discussed. Considered model of the inertial foundation is described by three parameters.

Drivers of human attitudes towards wolves Canis lupus in Kazakhstan

People and Nature, EarlyView.
Abstract Kazakhstan is recognized as a key stronghold for the grey wolf (Canis lupus). Nonetheless, the wolf status and the dynamics of human‐wolf coexistence in the region remain poorly understood. This study aims to fill that gap by exploring current attitudes towards wolves in Kazakhstan and identify the underlying drivers of these attitudes.

Damping by heat conduction in the Timoshenko system: Fourier and Cattaneo are the same

, 2013
We consider the Cauchy problem for the one-dimensional Timoshenko system coupled with heat conduction, wherein the latter is described by either the Cattaneo law or the Fourier law.

Free and Forced Vibrations of an Axially-Loaded Timoshenko Multi-Span Beam Carrying a Number of Various Concentrated Elements

Shock and Vibration, 2012
In the existing reports regarding free and forced vibrations of the beams, most of them studied a uniform beam carrying various concentrated elements using Bernoulli-Euler Beam Theory (BET) but without axial force. The purpose of this paper is to utilize

Deformation and strength of grouted sleeve connectors in pre‐fabricated concrete structures: Mechanisms and analytical modeling

Structural Concrete, EarlyView.
Abstract Grouted sleeve connectors (GSCs) are widely used in precast/prefabricated concrete structures. To ensure force transfer, connectors are often overdesigned in length. This practice has an unintended consequence of reducing the plastic deformation capacity of the connection region and hence the displacement ductility of the precast structure as ...

Shaped electrodes for adaptive X‐ray optics

Journal of Synchrotron Radiation, EarlyView.
For adaptive X‐ray optics on high‐performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and

Analysis of Critical Velocities for an Infinite Timoshenko Beam Resting on an Elastic Foundation Subjected to a Harmonic Moving Load

Shock and Vibration, 2014
Critical velocities are investigated for an infinite Timoshenko beam resting on a Winkler-type elastic foundation subjected to a harmonic moving load. The determination of critical velocities ultimately comes down to discrimination of the existence of ...

Simultaneous measurements of solid–liquid interfaces and bulk liquids using soft X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, EarlyView.
Simultaneous measurement methods have been developed for soft X‐ray absorption spectroscopy of solid–liquid interfaces using the electron‐yield method and bulk liquids using the transmission method.Simultaneous measurement methods for soft X‐ray absorption spectroscopy (XAS) of solid–liquid interfaces and bulk liquids have been developed.

Exponential decay rate for a Timoshenko beam with boundary damping

, 2004
The exponential decay rate of a Timoshenko beam system with boundary damping is studied. By asymptotically analyzing the characteristic determinant of the system, we prove that the Timoshenko beam system is a Riesz system; hence, its decay rate is ...
