Análises térmica e energética no pré-aquecimento do revestimento refratário de panelas de aciaria via métodos numéricos e experimentais
(Universidade Federal de São Carlos, 2022-04-28)
Preheating the refractory lining of industrial equipment usually consumes substantial amounts of energy. This step is usually time consuming and impacts the costs and productivity of several economic sectors. Therefore, ...
Parâmetros de monitoramento na produção industrial de componentes em zircônia parcialmente estabilizada com óxido de magnésio
(Universidade Federal de São Carlos, 2012-02-08)
Zirconia has been widely applied on production of structural components, mainly due to its great mechanical properties. However, these properties are associated to the zirconia tetragonal and cubic phases, which are stable ...
Calibração do modelo de Drucker-Prager/CAP para simulação numérica do processo de prensagem a frio de pós metálicos
(Universidade Federal de São Carlos, 2015-03-27)
An experimental procedure for the calibration of Drucker-Prager/Cap model, using
the digital image correlation technique, is presented. The elastic properties were
characterized by fitting stress vs. strain curves recorded ...
Caracterização da interface de tubo bimetálico cladeado fundido por centrifugação
(Universidade Federal de São Carlos, 2015-03-27)
Bimetallic pipes represent a solution for cost reduction to pipelines in the oil and
gas industry, because they combine two materials with distinct characteristics in
the pipe manufacturing: a HSLA steel, constituting ...
Efeitos de degradação e de alterações microestruturais do polímero no desempenho mecânico estático de juntas híbridas de polieterimida (PEI) e alumínio produzidas por F-ICJ
(Universidade Federal de São Carlos, 2016-02-29)
This master thesis aims to study hybrid joints of polyetherimide (PEI) and aluminum 6082-T6 produced by Friction-based Injection Clinching Joining (FICJ). The influences of the process parameters in the frictional heat and ...
Compatibilização química em compósitos de PLA reforçados com fibras de sisal
(Universidade Federal de São Carlos, 2018-07-13)
Even though poly(lactic acid) (PLA) is fragile under impact and has low toughness, the polymer stands out for its stiffness and high tensile strength. This polymer is an interesting material not only for short-term ...
Desenvolvimento de Nanoblendas PLA/EVOH biodegradáveis com características de barreira a gases e vapores
(Universidade Federal de São Carlos, 2018-07-20)
Poly (lactic acid) (PLA) is a non-toxic, transparent and biodegradable aliphatic polyester, produced from renewable raw materials. This polymer meets several requirements for packaging applications, but is fragile and has ...
Ligas Sn-Ni: efeitos da taxa de resfriamento e da microestrutura nas propriedades mecânicas de tração
(Universidade Federal de São Carlos, 2018-02-28)
The present investigation examined the microstructural arrangements formed during the transient solidification of the eutectic Sn-0.2wt.%Ni and the hypereutectic Sn-0.5wt.%Ni alloys using two different substrates as mold ...
