Complex modal analysis of a vertical rotor through finite element method
(2012)
Natural frequencies were analyzed (axial, torsional and flexural) and frequency response of a vertical rotor with a hard disk at the edge through the classical and complex modal analysis. The mathematical modeling was based ...
Generalized apostol-type polynomial matrix and its algebraic properties

Análise de vigas de Timoshenko pelo Método dos Elementos Finitos
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Civil, 2019-05-23)
This work aims to analyze the structural behavior of beams in linear elastic regime by the Finite Element Method (MEF) based on the Timoshenko Beam Theory. A numerical study of the problem was developed and used as a base ...
Estudo, dimensionamento e análise de um absorvedor dinâmico de vibração do tipo passivo
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2021-08-17)
This work presents an evaluation, in comparison with the attenuation of the vibration amplitude of a beam modeled according to the Euler-Bernoulli theory, applying beam-type passive dynamic vibration absorbers. Therefore, ...
Friction-induced artifact in atomic force microscopy topographic images
(Universidade Federal de Minas GeraisUFMG, 2014-03-20)
In Contact Mode Atomic Force Microscopy (CM-AFM), a cantilever with a sharp tip on its end is employed to acquire topographic information. Such acquisition is normally made by monitoring the deflection of the cantilever ...
Applicability of the theory of non-local elasticity to the mechanical behavior of solids using FEM
(Universidad de los AndesMaestría en Ingeniería CivilFacultad de Ingeniería, 2023-01-25)
Throughout this thesis, we propose several simulations of nanostructures in order to determine the range of applications for non-local elasticity. The simulations involve changes in geometry, material, size, and non-local ...
EVALUATING VIBRATIONS ON A SMALL-SCALE MODEL OF A TIMBER FOOTBRIDGE
(UNIV BIO-BIO, 2011)
In Brazil, the study of pedestrian-induced vibration on footbridges has been undertaken since the early 1990s, for concrete and steel footbridges. However, there are no recorded studies of this kind for timber footbridges. ...
Eigenproblems in timber structural elements with uncertain properties
(Springer, 2016-07)
A stochastic model of sawn timber structural elements of Argentinean Eucalyptusgrandis is applied to the study of two eigenproblems. One is the free vibrations problem which, after being solved, yields the natural frequencies ...
Free Vibrations of Beam System Structures with Elastic Boundary Conditions and an Internal Elastic Hinge
(Hindawi Publishing Corporation, 2013-09)
The study of the dynamic properties of beam structures is extremely important for proper structural design. This present paper deals with the free in-plane vibrations of a system of two orthogonal beam members with an ...
