    Computational Particle Mechanics (2023). Vol.10 (1), pp. 121-141

    Abstract
    The main objective of this research is to formulate and couple technologies for modeling discrete and continuous media using real particle morphologies. To that end, two coupled [...]

  • Water (2021). 13(17), 2387

    Abstract
    Dam safety assessment is typically made by comparison between the outcome of some predictive model and measured monitoring data. This is done separately for each response [...]

  • Archives of Computational Methods in Engineering (2020). 27 (5), 1681-1707

    Abstract
    Double-curvaturedamsareunique structures for several reasons. Their behaviour changes significantly after joint grouting, when they turn from a set of independent cantilevers [...]

  • J. Irazábal's Conference proceedings (2019). 1

    Abstract
    Conventional and high-speed train lines are being constructed all over the world with the objective of improving the mobility of both people and goods. Most of these infrastructures [...]

  • J. Irazábal's Conference proceedings (2019). 1

    Abstract
    Rail transport, both for people and goods, is becoming increasingly significant all over the world, which is reflected in the great growth of conventional and high-speed train [...]

  • Computational Particle Mechanics (2019). Vol. 6 (4), pp 545–559

    Abstract
    The discrete element method (DEM) is an emerging tool for the calculation of the behaviour of bulk materials. One of the key features of this method is the explicit integration [...]

  • Int. J. Numer. Anal. Meth. Geomech. (2016). Vol. 40 (6), pp. 809-826

    Abstract
    Landslide‐generated impulse waves may have catastrophic consequences. The physical phenomenon is difficult to model because of the uncertainties in the kinematics of the [...]

  • Computers and Geotechnics (2017). Vol. 85, pp. 220-229

    Abstract
    The Discrete Element Method (DEM) was found to be an effective numerical method for the calculation of engineering problems involving granular materials. [...]

  • (2018). Fourth International Conference on Railway Technology: Research, Development and Maintenance (RAILWAYS 2018))

    Abstract
    The development of high-speed train lines has increased significantly during the last decades leading to more demanding loads in railway infrastructures. Most of these infrastructures [...]

  • (2017). V International Conference on Particle-Based Methods (PARTICLES 2017)

    Abstract
    Railway ballast is a layer of granular material that resists to vertical and horizontal loads, produced by the passing train over the rail. The calculation of this kind of [...]
