Efficient and accurate approach for powder compaction problems
(2003-02)
Article.
Accés obert
Article.
Accés obert
In this paper, a new approach for powder cold compaction simulations is presented. A density-dependent plastic model within the framework of finite strain multiplicative hyperelastoplasticity is used to describe the highly ...
A hybridizable discontinuous Galerkin phase-field model for brittle fracture with adaptive refinement
(John Wiley & sons, 2020-03-30)
Article.
Accés obert
Article.
Accés obert
In this paper, we propose an adaptive refinement strategy for phase-field models of brittle fracture, which is based on a novel hybridizable discontinuous Galerkin (HDG) formulation of the problem. The adaptive procedure ...
Comparative study of different discrete element models and evaluation of equivalent micromechanical parameters
(2012-06)
Article.
Accés obert
Article.
Accés obert
Comparative studies of different discrete element models of a rock-type material are presented. The discrete element formulation employs spherical particles with the cohesive interaction model combining linear elastic ...
Numerical estimation of the bearing capacity of resistance spot welds in martensitic boron steels using a J-integral fracture criterion
(2018-08-01)
Article.
Accés obert
Article.
Accés obert
Predicting the bearing capacity of resistance spot welds (RSW) during vehicle crash tests has become a crucial task for the automotive industry, since the recent introduction of advanced high strength steels (AHSS) such ...
El ensayo europeo de sensibilidad al agua y su relación con los ensayos normalizados en España
(2008-10)
Article.
Accés obert
Article.
Accés obert
La entrada en vigor, desde marzo del presente año, de la nueva normativa europea referente a los criterios de especificación y al control del sistema de producción de las mezclas bituminosas en caliente para empleo en obras ...
A stabilized mixed implicit Material Point Method for non-linear incompressible solid mechanics
(Springer, 2019-06)
Article.
Accés obert
Article.
Accés obert
In 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 ...
Reactive transport modeling of leaking CO2-saturated brine along a fractured pathway
(John Gale, 2015-11)
Article.
Accés obert
Article.
Accés obert
One concern regarding the underground storage of carbon dioxide (CO2) is its potential leakage from reservoirs. Over short period of time, the leakage risk is related mainly to CO2 as a separate supercritical fluid phase. ...
A consistent characteristic length for smeared cracking models
(John Wiley & sons, 1989-02)
Article.
Accés restringit per política de l'editorial
Article.
Accés restringit per política de l'editorial
A numerical scheme for crack modelling by means of continuous displacement fields is presented. In two-dimensional problems a crack is modelled as a limiting case of two singular lines (with continuous displacements, but ...
Elemental enriched spaces for the treatment of weak and strong discontinuous fields
(2017-01)
Article.
Accés obert
Article.
Accés obert
This paper presents a finite element that incorporates weak, strong and both weak plus strong discontinuities with linear interpolations of the unknown jumps for the modeling of internal interfaces. The new enriched space ...
