A micromorphic model for steel fiber reinforced concrete
(Elsevier, 2012-07)
A new formulation to model the mechanical behavior of high performance fiber reinforced cement composites with arbitrarily oriented short fibers is presented. The formulation can be considered as a two scale approach, in ...
Computational modeling of high performance steel fiber reinforced concrete using a micromorphic approach
(Springer, 2013-01)
A finite element methodology for simulating the failure of high performance fiber reinforced concrete composites (HPFRC),with arbitrarily oriented short fibers, is presented. The composite material model is based on a ...
Improvement of asphalt mixture performance with glass macro-fibers
(Elsevier, 2018-03)
Cracking is a common failure in concrete asphalt mixtures due to fatigue and low temperatures. For centuries fibers have been used to reinforce materials and short and long fibers have extensive use in Portland cement ...
Análise da eficiência do reforço estrutural com fibra de carbono em pilares curtos
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2013-05-14)
Concrete is the most usual material in constructions and considering its average lifespan of 50 years, eventually the structures will need to be strengthened or repaired. Another case in which it is necessary to apply a ...
A simple method for non-linear analysis of steel fiber reinforced concrete
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAO, 2010)
This paper proposes a physical non-linear formulation to deal with steel fiber reinforced concrete by the finite element method. The proposed formulation allows the consideration of short or long fibers placed arbitrarily ...
Multifield-based modeling of material failure in high performance reinforced cementitious composites
(CIMNE, 2013)
Cementitious materials such as mortar or concrete are brittle and have an inherent weakness in resisting tensile stresses. The addition of discontinuous fibers to such matrices leads to a dramatic improvement in their ...
Numerical simulation of the three edge bearing test of steel fiber reinforced concrete pipes
(Asociación Argentina de Mecánica Computacional, 2021)
Flexural strengthening of reinforced concrete beams with carbon fibers reinforced polymer (CFRP) sheet bonded to a transition layer of high performance cement-based compositeReforço à flexão de vigas de concreto armado com Tecido de Polímero Reforçado com Fibras de Carbono (PRFC) aderido a substrato de transição constituído por compósito cimentício de alto desempenho
(IBRACON - Instituto Brasileiro do Concreto, 2012)
Resistance to corrosion, high tensile strength, low weight, easiness and rapidity of application, are characteristics that have contributed to the spread of the strengthening technique characterized by bonding of carbon ...
