  • Automation and control in a submarine drill rig 

    Arriaga, Aldo; Devincenzi, M.; Pérez, N.; Deu, A.; Arroyo Alvarez de Toledo, Marcos (Society for Underwater Technology, 2017)
    Text en actes de congrés
    Accés obert
    Remotely operated submarine drills are gaining acceptance as offshore geotechnical investigation tools for they provide a more convenient and often cheaper solution to geotechnical drilling vessels. The MD500 is an underwater ...
  • Mechanical and Thermal DEM analyses of baled MSW storage 

    Arroyo Alvarez de Toledo, Marcos; Ciantia, Matteo Oryem (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Municipal solid waste is sometimes stored in baled form either before or after treatment. General design requirements for MSW landfills, such as slope stability and lining long-term integrity are still relevant for bale ...
  • THM analysis of compacted clay liner response to baled municipal waste 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Isus, Andreu (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Heat is generated in municipal waste containment facilities due to the chemical and biochemical evolution of waste. Sometimes it is required to check if the level of heat generated during the deposit lifetime may damage ...
  • Periodic cells for large-scale problem initialization 

    Ciantia, Matteo Oryem; Arroyo Alvarez de Toledo, Marcos; Zhang, Ningning; Emam, Sacha (EDP Sciences, 2017)
    Text en actes de congrés
    Accés obert
    In geotechnical applications the success of the discrete element method (DEM) in simulating fundamental aspects of soil behaviour has increased the interest in applications for direct simulation of engineering scale boundary ...
  • Numerical analysis of desiccation, shrinkage and cracking in low plasticity clayey soils 

    Levatti, Hector Ulises; Prat Catalán, Pere; Ledesma Villalba, Alberto (2017)
    Comunicació de congrés
    Accés obert
    This paper presents a numerical study of the desiccation processes of low-plasticity clayey soils that usually result in shrinkage and often in cracking. For the theoretical development of the numerical model, concepts of ...
  • Discrete element modelling of granular column collapse tests with industrial applications 

    Torres Serra, Joel; Tunuguntla, Deepak R.; Denisen, Irana; Rodríguez Ferran, Antonio; Romero Morales, Enrique Edgar (International Centre for Numerical Methods in Engineering (CIMNE), 2017)
    Text en actes de congrés
    Accés obert
    Describing the behaviour of granular materials is a challenging issue for the industry. Our work concerns packaging industries where packing equipment is designed to handle a wide range of powders and bulk solids with ...
  • Flowability of granular materials with industrial applications: an experimental approach 

    Torres Serra, Joel; Romero Morales, Enrique Edgar; Rodríguez Ferran, Antonio; Caba, Joan; Arderiu, Xavier; Padullés, Josep-Manel; González, Juanjo (EPJ Web of Conferences, 2017)
    Text en actes de congrés
    Accés obert
    Designing bulk material handling equipment requires a thorough understanding of the mechanical behaviour of powders and grains. Experimental characterization of granular materials is introduced focusing on flowability. A ...
  • Analysis of vertical facing panel-joint gap in reinforced soil walls 

    Puig Damians, Ivan; Bathurst, Richard; Josa Garcia-Tornel, Alejandro; Lloret Morancho, Antonio; Lima, Juan (International Geosynthetics Society (IGS), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    This paper extends the numerical parametric study previously reported by the writers for the vertical load distribution and vertical gap compression between facing panel units in steel reinforced soil walls ranging in ...
  • Modelling the mechanical behaviour of Callovo-Oxfordian argillite: formulation and application 

    Gens Solé, Antonio; Mánica Malcom, Miguel Ángel; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (Springer, 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The paper presents a constitutive model for argillaceous rocks, developed within the framework of elastoplasticity, that includes a number of features that are relevant for a satisfactory description of their hydromechanical ...
  • Heave of a building on Keuper anhydritic formation 

    Ramon Tarragona, Anna; Alonso Pérez de Agreda, Eduardo (International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    The development of fissures in a building placed at the site of an ancient quarry excavated in a Keuper formation motivated a detailed in-situ investigation of the foundation material. Severe fissures and cracks were present ...
  • Analysis of strain localization with a non-local plasticity model 

    Mánica Malcom, Miguel Ángel; Gens Solé, Antonio; Vaunat, Jean; Ruiz Restrepo, Daniel Felipe (2017)
    Text en actes de congrés
    Accés obert
    Strain localization can be defined as the accumulation of deformations in narrow zones, in the form of shear bands or cracks, commonly observed in several geomaterials like concrete, rocks, dense sands, or stiff fine-grained ...
  • Simulation of penetration problems in geomechanics 

    Gens Solé, Antonio; Arroyo Alvarez de Toledo, Marcos; Carbonell Puigbó, Josep Maria; Ciantia, Matteo Oryem; Monforte Vila, Lluís (2017)
    Text en actes de congrés
    Accés obert
    The simulation of penetration problems in geomaterials is a challenging problem as it involves large deformations and displacements as well as strong non-linearities affecting material behaviour, geometry and contact ...
