Simulação numérica da influência da carga excêntrica e da altura do embutimento da estaca no comportamento estrutural de blocos rígidos de concreto armado sobre duas estacas
(Universidade Federal de São Carlos, 2024-03-20)
Deep foundations, such as piles and caissons, are responsible for supporting buildings and rely on cap blocks to distribute loads to the soil. Therefore, correct block design and execution are essential processes to ensure ...
Desenvolvimento e estudo de memristores baseados em redes de nanofios de SnO2
(Universidade Federal de São Carlos, 2024-01-17)
In this work, memristors were produced based on tin dioxide nanowire networks (𝑆𝑛𝑂2). These nanowires were synthesized by the VLS (Vapor-Liquid-Solid) method. The nanowire structural analysis via X-ray diffraction (XRD) ...
Influência da demolição seletiva na redução de impactos ambientais sob a óptica da avaliação do ciclo de vida
(Universidade Federal de São Carlos, 2024-02-29)
The concern about waste generated by demolition processes has driven the search for more
sustainable methods for this practice. In Brazil, since the cancellation of ABNT NBR 5682:1977
in 2008, there has been a lack of ...
Microstructure, corrosion, and wear resistance of a boron-modified duplex stainless steel produced by laser powder bed fusion
(Universidade Federal de São Carlos, 2024-03-18)
A duplex stainless steels (DSS) containing 0.3 and 0.6 wt.% of boron were produced by laser powder bed fusion (L-PBD) with parameters based on Box-Behnken design. The microstructure was evaluated by XRD, OM, SEM, EBSD, ...
Passivação do aço carbono em solução de poros de compósitos cimentícios com substituição de pó de vidro
(Universidade Federal de São Carlos, 2024-03-22)
Society seeks solutions for sustainable concrete and mortar, with less use of natural resources and lower CO2 emissions. Therefore, the use of alternative materials to cement and/or natural aggregates comes to solve this ...
