Advances in particle packing algorithms for generating the medium in the Discrete Element Method
(2019-03)
Article
Restricted access - publisher's policySeveral theoretical contributions in order to establish a particle packing methodology are presented. In this respect, a generic formulation of a new method for packing particles based on a constructive advancing front ... -
A cut finite element method for the solution of the full-potential equation with an embedded wake
(Springer, 2019-05)
Article
Restricted access - publisher's policyPotential flow solvers represent an appealing alternative for the simulation of non-viscous subsonic flows. In order to deliver accurate results, such techniques require prescribing explicitly the so called Kutta condition, ... -
A stabilized mixed implicit Material Point Method for non-linear incompressible solid mechanics
(Springer, 2018-10)
Article
Restricted access - publisher's policyIn this work a stabilized mixed formulation for the solution of non-linear solid mechanics problems in nearly-incompressible conditions is presented. In order to deal with high material deformation, an implicit Material ... -
Comparative study on sheet metal forming processes by numerical modelling and experiment
(1992-09)
Article
Open AccessIn this paper some results of a wide experimental program are presented and compared with some finite element solution of sheet metal forming problems using a viscous shell formulation. -
The intrinsic time for the streamline upwind/Petrov-Galerkin formulation using quadratic elements
(1992-01)
Article
Open AccessIn this paper the functions of the Péclet number that appear in the intrinsic time of the streamline upwind/Petrov-Galerkin (SUPG) formulation are analyzed for quadratic elements. Some related issues such as the computation ... -
A non-linear finite element method on unstructured meshes for added resistance in waves
(2018-06-15)
Article
Restricted access - publisher's policyIn this work a finite element method is proposed to solve the problem of estimating the added resistance of a ship in waves in the time domain and using unstructured meshes. Two different schemes are used to integrate the ... -
Modeling polycrystalline materials with elongated grains
(John Wiley & sons, 2019-04)
Article
Restricted access - publisher's policyA novel algorithm to reproduce the arrangement of grains in polycrystalline materials was recently published by the authors. In this original approach, a dense package of circles (or spheres) with the same distribution as ... -
Propuesta para la futura norma de aislamiento sísmico de edificaciones en Colombia
(2018-10-01)
Article
Open AccessEn Colombia no existe una normativa propia para el diseño de edificaciones con aislamiento sísmico de base; el limitado número de edificios aislados existentes en el país han sido diseñados según alguno de los documentos ... -
Predicción de fracturas en estructuras de hormigón combinando los métodos de elementos finitos y de elementos discretos
(2018-12)
Article
Restricted access - publisher's policyEl presente trabajo plantea los conceptos básicos y de aplicación de la estrategia que combina los métodos de elementos finitos y de elementos discretos para el estudio de la propagación de fracturas en estructuras de ... -
Análisis no lineal de tanques criogénicos bajo cargas térmicas

New formulation for estimating the damping parameter of the Kelvin-Voigt model for seismic pounding simulation
(2018-11-15)
Article
Open AccessSeismic pounding between adjoining buildings frequently causes serious damage; although collision can be avoided with proper separation, can still occur due to code non-fulfillment, loose requirements of old codes, and ... -
A simplified scheme for piezoelectric anisotropic analysis in human vertebrae using integral methods
(2018-06)
Article
Open AccessThis paper outlines a computational model for the analysis of the piezoelectric behaviour of the vertebral body remodelling process. Particular attention is paid to the algorithms for the simulation of the stress energy ...
