Numerical Simulations of the Flow Around a Spinning Projectile in Subsonic Regime
(Planta Piloto de Ingeniería Química, 2008-12)
The unsteady flow around a 155 mm projectile governed by the Navier-Stokes (NS) equations is numerically solved with a Large Eddy Simulation (LES) scheme, together with the SubGrid Scale (SGS) solved by a Smagorinsky model ...
Ultrasonic fatigue tests at high temperature on an austenitic steel
(Elsevier Ltd, 2012-12)
The objective of this paper is to study the gigacycle fatigue behavior of an austenitic steel at temperatures of 600 °C and 700 °C under fully reverse loading (R=−1). Numerical simulation by finite element method (FEM) was ...
Bounded renormalization with continuous penalization for level set interface capturing methods
(John Wiley & Sons Ltd, 2010-11)
In this work, a reinitialization procedure oriented to regularize the level set (LS) function field is presented. In LS approximations for two-fluid flow simulations, a scalar function indicates the presence of one or ...
Lubrication model of a knee prosthesis, with non newtonian fluid and porous rough material
(Planta Piloto de Ingeniería Química, 2009-03)
Tibial component of knee prostheses, made of ultra high molecular weight polyethylene (UHMWPE), experiences a high degree of wear and may be expected to last twelve years on average. In this work, a steady state one-dimensional ...

Convergence of Adaptive Finite Element Methods
(Society for Industrial and Applied Mathematics, 2002-12)
Adaptive finite element methods (FEMs) have been widely used in applications for over 20 years now. In practice, they converge starting from coarse grids, although no mathematical theory has been able to prove this assertion. ...
Convergence of an adaptive Kačanov FEM for quasi-linear problems
(Elsevier Science, 2011-04)
We design an adaptive finite element method to approximate the solutions of quasi-linear elliptic problems. The algorithm is based on a Kačanov iteration and a mesh adaptation step is performed after each linear solve. The ...
