Vibrational problems of timber beams with knots considering uncertainties
(Brazilian Society of Mechanical Sciences & Engineering, 2015-12-12)
A stochastic model of the dynamic behavior of sawn timber beams of Argentinean Eucalyptus grandis is herein presented. The aim of this work is to study the influence of the timber knots in the dynamical response of timber ...
Non-linear dynamic response of a rotating thin-walled composite beam
(Asociación Argentina de Mecánica Computacional, 2010-11)
The nonlinear planar response of a cantilever rota ting slender beam to a principal parametric resonance of its first bending mode is analyzed. The equation of motion is obtained in the form of an integro-partial differential ...
Mode I stress intensity factor for cracked thin-walled composite beams
(Elsevier Science, 2013-10)
In this paper, we present an analytical method to determine the mode I stress intensity factor for thin-walled beams made of laminated composites. The technique relies on the concept of crack surface widening energy release ...
Linear viscoelastic analysis of straight and curved thin-walled laminated composite beams
(Pergamon-Elsevier Science Ltd, 2008-06)
This paper is devoted to study the behavior, in the range of linear viscoelasticity, of shear flexible thin-walled beam members constructed with composite laminated fiber-reinforced plastics. This work appeals to the ...
Vibrations of axially moving flexible beams made of functionally graded materials
(Elsevier, 2008-02)
Problems related to the vibrations of axially moving flexible beams made of functionally graded materials are addressed. The problem of an axially moving beam may be interpreted as a telescopic system in which the mass is ...
Dynamics of thin walled composite beams: Analysis of parametric uncertainties
(Elsevier, 2013-05)
This article is concerned with the stochastic dynamic analysis of structures constructed with composite materials. Depending on many aspects (manufacturing process, material uncertainty, boundary conditions, etc.) real ...
Dimensionamento de um pavimento misto aço-concreto com aberturas na alma das vigas
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2020-08-20)
This study presents the design of a steel-concrete composite floor with beams with holes in the web. The work starts from a bibliographic review that introduces the elements of a composite floor, highlighting its constructive ...
A simple and accurate generalized shear deformation theory for beams
(Elsevier, 2015-12)
This paper presents a static analysis of functionally graded (FG) single and sandwich beams by using a simple and efficient 4-unknown quasi-3D hybrid type theory, which includes both shear deformation and thickness stretching ...
