Non-uniform Euler-Bernoulli beams’ natural frequenciesFrecuencias propias de vigas Euler-Bernoulli no uniformes
(INGENIERÍA E INVESTIGACIÓN, 2011-02-10)
This paper has studied the problem of natural frequencies
for Euler-Bernoulli beams having non-uniform crosssection. The numerically-obtained solutions were compared to asymptotic solutions obtained by the WentzelKramers-Brillouin ...
A Transmission Problem for Euler-Bernoulli beam with Kelvin-Voigt Damping
(Natural Sciences Publishing Corporation, 2011-01-01)
In this work we consider a transmission problem for the longitudinal displacement of a Euler-Bernoulli beam, where one small part of the beam is made of a viscoelastic material with Kelvin-Voigt constitutive relation. We ...

A solução fundamental na obtenção das frequências naturais e autofunções de um sistema de viga dupla Euler-Bernoulli com camada elástica e força axial
(Universidade Federal de Santa MariaBrasilMatemáticaUFSMPrograma de Pós-Graduação em MatemáticaCentro de Ciências Naturais e Exatas, 2022-08-18)
In this work we approach a double Euler-Bernoulli beam system with axial force coupled by
an elastic layer. We performed a matrix formulation for the system of equations and for the
boundary conditions, which allows ...
Autofunções e frequências de vibração do modelo Euler-Bernoulli para vigas não-clássicas
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2011-07-18)
This paper presents a methodology for determining eigenfunctions and frequencies
of the Euler-Bernoulli model for elastic beams that can include damping and devices
located at intermediate or end points of the beam. The ...
Modeling and experimental validation of two adjacent portal frame structures subjected to vibro-impact
(Universidade Federal da Grande DouradosBrasilFaculdade de EngenhariaUFGD, 2020)
Modal Analysis of a Beam with a Tip Rotor by Using a Fundamental Response
(2003-12-08)
The shape modes of a damped-free beam model with a tip rotor are determined by using a dynamical basis that is generated by a fundamental spatial free response. This is a non-classical distributed model for the displacements ...
