Property of growth determined by the spectrum of operator associated to Timoshenko system with memory [PDF]

Mathematica Moravica, 2019
In this manuscript we prove the property of growth determined by spectrum of the linear operator associated with the Timoshenko system with two histories.

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

Identifying Customer Needs from User-Generated Content

, 2017
Firms traditionally rely on interviews and focus groups to identify customer needs for marketing strategy and product development. User-generated content (UGC) is a promising alternative source for identifying customer needs. However, established methods

Uniform controllability for Kirchhoff and Mindlin-Timoshenko elastic systems

Electronic Journal of Differential Equations, 1999
The Mindlin-Timoshenko operator is a perturbation of the Kirchhoff operator and it is well known that there exist solutions to the exact controllability problem for their associated systems.

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.

Surface effect on the resonant frequency of Timoshenko nanobeams

, 2017
The dynamic behavior of a Timoshenko nanobeam would be significantly different from a macro-one due to the large ratio of surface area to volume of nanomaterials.

Decay rate of the solutions to the Cauchy problem of the Lord Shulman thermoelastic Timoshenko model with distributed delay

Demonstratio Mathematica
In this study, we address a Cauchy problem within the context of the one-dimensional Timoshenko system, incorporating a distributed delay term. The heat conduction aspect is described by the Lord-Shulman theory.

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 ...

Exponential stabilty for a Timoshenko system with nonlocal delay

Trends in Computational and Applied Mathematics, 2020
The purpose of this paper is to study  the Timoshenko system with nonlocal time-delayed condition. The well-posedness is proved  by Hille-Yosida theorem.

Frequency spectra of nonlocal Timoshenko beams and an effective method of determining nonlocal effect

, 2017
Three critical frequencies independent of boundary conditions together with a critical length, which determine the vibration behaviors of a nonlocal Timoshenko beam, are identified.
