Extension of the classical linear slip model for fluid-saturated fractures: Accounting for fluid pressure diffusion effects
(Blackwell Publishing, 2017-02)
We develop extended boundary conditions based on the linear slip model that account for the impact of wave-induced fluid pressure diffusion between a fracture and its embedding background on the stiffening effect of the ...
Tsunami modeling to validate slip models of the 2007 Mw8.0 Pisco earthquake, central Peru
(Springer, 2013)
Following the 2007, August 15th, M w 8.0, Pisco earthquake in central Peru, Sladen et al. (J Geophys Res 115: B02405, 2010) have derived several slip models of this event. They inverted teleseismic data together with ...
Coupled axial/torsional vibrations of drill-strings by means of non-linear model
(Pergamon-Elsevier Science Ltd, 2007-07)
In the present work a geometrically non-linear model is presented to study the coupling of axial and torsional vibrations on a drill-string, which is described as a vertical slender beam under axial rotation. It is known ...
Discontinuous Galerkin methods for solving the acoustic wave equation
(Asociación Argentina de Mecánica Computacional, 2013-11)
In this work we develop a numerical simulator for the propagation of elastic waves by solving the one-dimensional acoustic wave equation with Absorbing Boundary Conditions (ABC’s) on the computational boundaries using ...
Efficient Bayesian uncertainty estimation in linear finite fault inversion with positivity constraints by employing a log-normal prior

Estudos numéricos da formulação natural do tensor: aplicação em escoamentos viscoelásticos com escorregamento
(Universidade Estadual Paulista (Unesp), 2021-03-15)
Neste projeto investiga-se numericamente escoamentos com escorregamento utilizando uma formulação alternativa para descrever o tensor que representa os efeitos viscoelásticos do fluido. São analisados o caso Newtoniano e, ...
