Aspect ratio-and size-controlled patterned triangulations of parametric surfaces 

Ruíz, Óscar E.; Peña, Sebastián; Duque, Juan (2007-02)
A method to produce patterned, controlled size triangulation of Boundary Representations is presented -- Although the produced patterned triangulations are not immediately suited for fast visualization, they were used in ...

Spring–particle model for hyperelastic cloth 

García, Manuel; Gómez, Mario; Ruíz, Óscar; Boulanger, Pierre (2005-05)
This article presents a computational model to simulate the deformation of hyperelastic fabrics -- The model is based on a spring−particle approach and it simulates the interaction of a textile tissue with a forming body ...

Spring–particle model for hyperelastic cloth 

García, Manuel; Gómez, Mario; Ruíz, Óscar; Boulanger, Pierre (Universidad Nacional de Colombia, 2007-03)
Este artículo presenta un modelo computacional para la simulación de telas hiperelásticas -- El modelo propuesto tiene un enfoque multi−partículas y simula la interacción de un material textil con un objeto deformante -- ...

Numerical analysis of wave propagation in fluid-filled deformable tubes 

Uribe, David; Steeb, Holger; Saenger, Erik H.; Kurzeja, Patrick; Ruíz, Óscar (WILEY-VCH Verlag, 2013-11-29)
The theory of Biot describing wave propagation in fluid saturated porous media is a good effective approximation of a wave induced in a fluid-filled deformable tube -- Nonetheless, it has been found that Biot’s theory has ...

Gabriel-constrained Parametric Surface Triangulation 

Ruíz, Óscar E.; Cadavid, Carlos; Lalinde, Juan G.; Serrano, Ricardo; Peris-Fajarnés, Guillermo (2008-10)
The Boundary Representation of a 3D manifold contains FACES (connected subsets of a parametric surface S : R2−R3) -- In many science and engineering applications it is cumbersome and algebraically difficult to deal with ...

Geometric modeling in design of naval elements 

Ruíz S., Óscar E.; Leiceaga Baltar, Xoán; Rodrígez Pérez, Manuel; Prieto Villar, José (2003)
Boundary Representations (B-Reps) of actual solid parts are correct from the geometrical and topological points of view -- However, when the solid to model has extreme slender ratios, the rigid rules of the B-Rep force a ...

Force-Displacement Model of Compliant Mechanisms using Assur Sub-Chains 

Durango, S.; Correa, J.; Ruíz, O.; Aristizábal, M.; Restrepo-Giraldo, J.; Achiche, S. (2011-06)
This article develops a modular procedure to perform force-displacement modeling of planar flexurebased compliant mechanisms (CMs) -- The procedure is mostly suitable for planar lumped CMs -- To achieve the position analysis ...

FEA-driven Geometric Modelling for Meshless Methods 

Ruíz, Óscar; Granados, Miguel; Cadavid, Carlos (Springer Paris, 2005-11)
Optimized Boolean Operations against orthogonal Fixed Grids (FG) for 2-manifold construction in quasi-meshless methods for Finite Element Analysis are presented -- A Piecewise Linear (PL) or Boundary Representation (B-Rep) ...

Geometry simplification for modeling of porous materials 

Ruíz, Óscar E.; Cadavid, Esteban; Osorno, María C.; Uribe, David; Steeb, Holger (2015)
Porous and lattice materials have become everpresent in applications such as medicine, aerospace, design, manufacturing, art, entertainment, robotics, material handling, etc -- However, their application is impeded by the ...

Fixed grid finite element analysis for 3D structural problems 

García, Manuel J.; Henao, Miguel A.; Ruíz, Óscar E. (World Scientific Publishing Co., 2005)
Fixed Grid (FG) methodology was first introduced by García and Steven as an engine for numerical estimation of two-dimensional elasticity problems -- The advantages of using FG are simplicity and speed at a permissible ...
