An experimental study on the post-cracking behaviour of hybrid Industrial/Recycled steel fibre-reinforced concrete
(Elsevier, 2015-09)
This paper investigates the mechanical behaviour of FRC made with both Industrial and Recycled Steel Fibres recovered from waste tyres. Specimens of various mixtures, characterised by the same volume fraction of fibres, ...
Effect of the fibre type on concrete impact resistance
(Elsevier, 2020-12)
Fibre Reinforced Concrete performance is evaluated in terms of bending residual stresses. Although fibre concrete is suitable for structures exposed to impacts and other extreme loads, there is not much information about ...
A numerical model for the description of the nonlinear behaviour of multi-leaf masonry walls
(ELSEVIER SCI LTD, 2008)
A nonlinear finite element model was developed to simulate the nonlinear response of three-leaf masonry specimens, which were subjected to laboratory tests with the aim of investigating the mechanical behaviour of multiple-leaf ...
A thermo-mechanical interface model for simulating the bond behaviour of FRP strips glued to concrete substrates exposed to elevated temperature
(Elsevier, 2015-01)
This paper proposes a model aimed at simulating the bond behaviour of Fiber Reinforced Polymer (FRP) laminates glued to concrete substrates and exposed to high temperature. Based on a previous model already formulated by ...
Methodology for the analysis of post-tensioned structures using a constitutive serial-parallel rule of mixtures: Large scale non-linear analysis
(Elsevier, 2019-05)
The main purpose of this paper is to develop a reliable method based on a three-dimensional (3D) finite-element (FE) model to simulate the constitutive behaviour of reinforced concrete structures strengthened with ...
A influência da saturação pós-compactação no comportamento resiliente de dois solos do Rio Grande do Sul empregados em subleito rodoviário
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2019-12-16)
Aiming to correct one of the predominant defects on brazilian pavements, the fatigue cracking, the National Dimensioning Method was developed, extinguishing the empirical approach applied to highways so far. The new method ...
Análise de degradação material, bifurcação e transição entre descontinuidades fracas e fortes através do método dos elementos de contorno
(Universidade Federal de Minas GeraisUFMG, 2016-04-29)
The implicit formulation of the boundary element method is applied to bidimensional problems of material failure involving, sequentially, inelastic dissipation with softening in continuous media, bifurcation and transition ...
Experimental and numerical analysis of drop-weight low-velocity impact tests on hybrid titanium composite laminates
(SAGE Publications, 2016-11-01)
An experimental and numerical study on low-velocity impact responses on [Ti/0/90]s hybrid titanium composite laminates (HTCLs) is presented. Different energy levels from 10 to 40 J are investigated using a drop-weight ...
Dependência estrutural da capacidade de rotação plástic em vigas de concreto armado
(2010-12-01)
Summary In this work the structural dependence of plastic rotation capacity in RC beams is evaluated using the Finite Element Method. The objective is to achieve a better understanding of the non-linear behavior of reinforced ...
