A frame invariant and path-independent geometrically exact thin walled composite beam element
(Asociación Argentina de Mecánica Computacional, 2010-11)
A geometrically exact, frame invariant and path independent beam finite element for composite thin - walled beams is presented. In the proposed formulation the virtual work equations are written as a function of generalized ...
Effects of electron-beam irradiation on HDPE/Brazil nut shell fiber composite
(Sao Paulo: ABEN, 2013, 2014)
Damping response of composites beams with carbon nanotubes
(Elsevier, 2014-04)
Damping response of composite beams with carbon nanotubes (CNTs) have been studied carrying out free vibration tests. Simple and sandwich beams are manufactured with aluminum, epoxy resin and different types of CNTs. For ...
Modeling and analysis of a Ball and Beam system including impacts and dry friction
(2014-01-01)
The Ball and Beam system is a common didactical plant that presents a complex nonlinear dynamics. This comes from the fact that the ball rolls over the beam, which rotates around its barycenter. In order to deduce the ...
Flexural performance of concrete beams reinforced with epoxy resin/glass and carbon fibers composites
(2021-01-01)
Factors such as project and execution errors, lack of maintenance and inspection, and increases in loading can cause deficiencies to reinforced concrete structures. In this regard, there is the necessity of the application ...
Non-linear model for stability of thin-walled composite beams with shear deformation
(Elsevier, 2005-10)
A geometrically non-linear theory for thin-walled composite beams is developed for both open and closed cross-sections and taking into account shear flexibility (bending and warping shear). This non-linear formulation is ...
Reliability-based evaluation of design guidelines for cold-formed steel-concrete composite beams
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2010)
This paper presents an analysis of design guidelines for steel-concrete composite beams, formed by concrete-filled cold-formed steel sections. The study is based on experimental results for connector resistance (push-out) ...
Dynamic stability of thin-walled composite beams under periodic transverse excitation
(Academic Press Ltd - Elsevier Science Ltd, 2009-03-31)
The dynamic stability of thin-walled composite beams subjected to transverse external force has been investigated in this paper. The analysis is based on a seven-degree-of-freedom shear-deformable beam theory. A geometrically ...
A geometrically exact composite thin-walled beam element for flexible multibody dynamics
(Asociación Argentina de Mecánica Computacional, 2011-11-04)
A geometrically exact thin-walled composite beam finite element for multibody applications is presented. In the proposed formulation the virtual work equations are written as a function of generalized strains, which are ...
