Avaliação do dano por choque térmico em concretos refratários via espectroscopia acústica ressonante não-linear
(Universidade Federal de São Carlos, 2012-03-02)
In this thesis the Non-linear Resonant Acoustic Spectroscopy Technique used to evaluate the mesoscopic non-linearity was incorporated into the Impulse Excitation Technique, which is extensively applied to the evaluation ...
Avaliação do comportamento mecânico de nanocompósito de PEEK/nHA sob curta e longa duração para aplicação como biomaterial
(Universidade Federal de São Carlos, 2012-04-27)
The main objectives of this dissertation were to study the short (tensile and impact) and long-term (fatigue) mechanical behavior of nanocomposites of poly(ether-ether-ketone), PEEK, with nanohydroxyapatite, nHA, for ...
Propriedades mecânicas das ligas Ti34Cu36Ni8Zr22 e (TiZr)80Co12Fe8
(Universidade Federal de São Carlos, 2012-03-23)
Bulk amorphous and nanocrystalline alloys have attracted great interest from the scientific community. Titanium based alloys have demonstrated potential for formation of amorphous. This study aimed at to evaluate the ...
Influência de polipropileno maleado no comportamento de fratura (EWF) de compósitos de polipropileno/fibra de vidro
(Universidade Federal de São Carlos, 2012-04-11)
Thermoplastic composites reinforced with short glass fibers, to be used in technical engineering applications, usually requires a good balance of properties, such as strength and tenacity. For the case of the composite of ...
Crescimento super e subcrítico de trincas em vidros e vitrocerâmicos analisado via indentacão
(Universidade Federal de São Carlos, 2012-07-02)
In this dissertation we quantified properties that may better describe the mechanical behaviour of different glasses and glass-ceramics of the Na2O-CaO-SiO2-P2O5 system, based on the Biosilicate®chemical composition developed ...
