A study on finite elements for capturing strong discontinuities
(John Wiley & sons, 2003-04)
Article.
Accés obert
Article.
Accés obert
The work focuses on the presently existing families of finite elements with embedded discontinuities and explores the possibilities of obtaining symmetric statically consistent finite elements that alleviate the stress-locking ...
A strain-based plastic viscous-damage model for massive concrete structures
(1998-05)
Article.
Accés obert
Article.
Accés obert
Within the framework of continuum damage mechanics, a new constitutive damage model for massive concrete is presented, mainly intended for the seismic analysis of gravity and arch dams. Consistent with thermodynamic ...
Simulation of construction of RCC dams. II: stress and damage
(2000-09)
Article.
Accés obert
Article.
Accés obert
The increasing number of roller compacted concrete (RCC) dams being built around the world demands accurate methodologies for the realistic short- and long-term evaluations of the risk of thermally induced cracking in these ...
Comparative study on sheet metal forming processes by numerical modelling and experiment
(1992-09)
Article.
Accés obert
Article.
Accés obert
In 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.
Multi-scale analysis of the early damage mechanics of ferritized ductile iron
(Springer, 2017-09)
Article.
Accés obert
Article.
Accés obert
A multi-scale analysis of the linear elastic and the early damage stages of ferritic ductile iron is introduced in this work. The methodology combines numerical and experimental analyses in the macro and micro scales. ...

Article.
Accés restringit per política de l'editorial
The paper focuses on the analysis of radial-gated spillways, which is carried out by the solution of a numerical model based on the finite element method (FEM). The Oliana Dam is considered as a case study and the discharge ...
Una formulación para el estudio, por el método de los elementos finitos, de la deformación de tuberías marinas durante su instalación
(1983-10)
Article.
Accés obert
Article.
Accés obert
La ejecución de emisarios submarinos para saneamiento y la instalación de tuberías para transporte de productos petrolíferos son ejemplos de la necesidad de conocer los esfuerzos y deformaciones que se producen en el tendido ...
Optimization-based design of a heat flux concentrator
(Nature Publishing Group, 2017)
Article.
Accés obert
Article.
Accés obert
To gain control over the diffusive heat flux in a given domain, one needs to engineer a thermal metamaterial with a specific distribution of the generally anisotropic thermal conductivity throughout the domain. Until now, ...

Stability and robustness issues in numerical modeling of material failure with the strong discontinuity approach
(2006-11)
Article.
Accés obert
Article.
Accés obert
Robustness and stability of the Continuum Strong Discontinuity Approach (CSDA) to material failure are addressed. After identification of lack of symmetry of the finite element formulation and material softening in the ...
