Post-buckling behavior of fluid-storage steel horizontal tanks
(Elsevier, 2018-05)
This paper focuses on the buckling and post-buckling of horizontal steel tanks with conical end-caps, supported on discrete saddles, under pressure caused by internal vacuum and liquid pressure. Linear bifurcation, as well ...
Months-long thousand-kilometre-scale wobbling before great subduction earthquakes
(Nature, 2020)
Megathrust earthquakes are responsible for some of the most devastating natural disasters(1). To better understand the physical mechanisms of earthquake generation, subduction zones worldwide are continuously monitored ...
Numerical modelling of three-phase immiscible flow in heterogeneous porous media with gravitational effects
(Elsevier Science BvAmsterdamHolanda, 2014)
Flow evolution of a metallic slurry during thixoextrusion of an automotive valve
(2004-12-01)
The aim of this work is to characterize a metallic slurry (Al-4.5%Cu) flow during thixoforming of an automotive valve. The necessary globular structure was obtained by first inoculating the alloy with TIBAL (5%Ti, 1%B, Al ...
Recovery of a Lamé parameter from displacement fields in nonlinear elasticity models
(Walter de Gruyter GMBH, 2022)
We study some inverse problems involving elasticity models by assuming the knowledge of measurements
of a function of the displaced field. In the first case, we have a linear model of elasticity with
a semi-linear type ...
Análise numérica do escoamento de fluido em tubos elásticos
(Universidade Estadual Paulista (Unesp), 2010-02-26)
O presente trabalho propõe-se a modelar, analisar, e comparar os efeitos do escoamento de um fluido dentro de um tubo elástico. Esses efeitos, por sua vez, serão ocasionados por uma variação de pressão nesse fluido. Para ...
Digital image correlation applied to the calculation of the out-of-plane deformation induced by the formation of roll waves in a non-Newtonian fluid
(Spie-Soc Photo-Optical Instrumentation Engineers, 2016)
A method based on digital image correlation (DIC) is implemented for measuring the height of the roll waves developed in a non-Newtonian fluid flowing on an inclined channel. A projector and a high-resolution digital camera, ...
