  • Towards higher temperatures in nuclear waste repositories 

    Gens Solé, Antonio; de Vasconcelos, R.; Olivella Pastallé, Sebastià (EDP Sciences, 2020-11)
    Article
    Open Access
    Recently, there is a tendency to explore the possibility of increasing the maximum design temperature in deep geological repositories for high-level nuclear waste and spent fuel. In the paper, a number of issues related ...
  • Modeling multiphase flow with a hybrid model based on the Pore-network and the lattice Boltzmann method 

    Puig Montella, Eduard; Yuan, Chao; Chareyre, Bruno; Gens Solé, Antonio (EDP Sciences, 2020-10)
    Article
    Open Access
    Lattice Boltzmann method (LBM) simulations provide an excellent description of two-phase flow through porous media. However, such simulations require a significant computation time. In order to optimize the computation ...
  • Investigation of the evolution of clay microstructure under different loading paths and impact on constitutive modelling 

    Cotecchia, Federica; Guglielmi, S.; Gens Solé, Antonio (Iris Publishers LLC, 2020-04)
    Article
    Open Access
    Part of a research programme concerning the investigation of the evolution of clay microstructure under different loading paths is presented. The material is a stiff over consolidated natural clay, strongly bonded by ...
  • 3D modelling of strip reinforced MSE walls 

    Puig Damians, Ivan; Bathurst, Richard; Olivella Pastallé, Sebastià; Lloret Morancho, Antonio; Josa Garcia-Tornel, Alejandro (Springer, 2020-08)
    Article
    Restricted access - publisher's policy
    This paper reports the results of 3D numerical modelling of a 6-m-high mechanically stabilised earth (MSE) wall constructed with concrete panels and steel or polymeric strip reinforcement. These systems pose numerical ...
  • Study of grain-scale effects in bulk handling using discrete element simulations 

    Torres Serra, Joel; Rodríguez Ferran, Antonio; Romero Morales, Enrique Edgar (2021-04)
    Article
    Restricted access - publisher's policy
    Industrial granular flow issues are affected by the particle properties and environmental conditions of the materials. To understand the impact of grain-scale effects on flowability, experimental testing should be complemented ...
  • Linking shape and rotation of grains during triaxial compression of sand 

    Rorato, Riccardo; Arroyo Alvarez de Toledo, Marcos; Andò, Edward; Gens Solé, Antonio; Viggiani, Gioacchino (2020-11)
    Article
    Restricted access - publisher's policy
    Particle shape has a strong effect on the mechanical response of coarse soils. This has been usually observed examining specimen-scale or engineering-scale responses, which are the sum of many microscale interactions. In ...
  • Discussion of “Stresses developed around displacement piles penetration in sand” by Z. X. Yang, R. J. Jardine, B. T. Zhu, and S. Rimoy 

    Butlanska, Joanna; Arroyo Alvarez de Toledo, Marcos (2015-03)
    Article
    Open Access
    The authors deserve praise for gathering together many different strands of evidence that clarify the mechanics of pile penetration in sand. In their review of numerical approaches to the problem, they correctly indicate, ...
  • Probabilistic mapping of earthquake-induced submarine landslide susceptibility in the South-West Iberian margin 

    Collico, Stefano; Arroyo Alvarez de Toledo, Marcos; Urgelés Esclasans, Roger; Gràcia Mont, Eulàlia; Devincenzi, M.J.; Pérez García, Norma (2020-11)
    Article
    Open Access
    The SW Iberian continental margin is well recognized as a tectonically active area, where major canyons and mass wasting events are both present. Earthquake triggered submarine landslides may cause tsunami and result in ...
  • Modelling gas flow in clay materials incorporating material heterogeneity and embedded fractures 

    Puig Damians, Ivan; Olivella Pastallé, Sebastià; Gens Solé, Antonio (Elsevier, 2020-12)
    Article
    Restricted access - publisher's policy
    A series of gas injection tests on compacted bentonite were carried out at the British Geological Survey. Tests measurements included pressure and rate of gas inflow, gas outflow volume as well as stresses and pore pressure ...
  • Hybrid multi-scale model for partially saturated media based on a pore network approach and lattice Boltzmann method 

    Puig Montellà, Eduard; Yuan, Chao; Chareyre, Bruno; Gens Solé, Antonio (Elsevier, 2020-10)
    Article
    Restricted access - publisher's policy
    A model combining the efficiency of the pore-network (PN) models and the accuracy of the lattice Boltzmann Method (LBM) is proposed. We introduce a multi-scale approach based on a decomposition of the granular assembly ...
  • Classification of granular materials via flowability-based clustering with application to bulk feeding 

    Torres Serra, Joel; Rodríguez Ferran, Antonio; Romero Morales, Enrique Edgar (2021-01-22)
    Article
    Restricted access - publisher's policy
    Feeder selection impacts the performance of bagging machinery throughout its life cycle, and yet it is usually based on qualitative assessments of flowability. We propose a data analysis methodology aimed at verifying the ...
  • Introduction: advances in landslide understanding 

    Alonso Pérez de Agreda, Eduardo; Pinyol Puigmartí, Núria Mercè (2019-09)
    Article
    Open Access
    Landslide research covers an extremely wide range of aspects: from triggering mechanisms to response of the unstable mass after failure, including transport, deposition, and interaction with protective structures. Advances ...
