    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 ...

  • An augmented Lagrangian formulation to impose boundary conditions for distortion based mesh moving and curving 

    Ruiz Gironès, Eloi; Gargallo Peiró, Abel; Sarrate Ramos, Josep; Roca Navarro, Xevi (Elsevier, 2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We formulate a mesh morphing technique as mesh distortion minimization problem constrained to weakly satisfy the imposed displacement of the boundary nodes. The method is devised to penalize the appearance of inverted ...

  • Approximation of immersed surfaces into a tetrahedral mesh generated by the meccano method 

    Socorro Marrero, Guillermo Valentín; Oliver Serra, Albert; Ruiz Gironès, Eloi; Cascón Barbero, José Manuel; Rodriguez Barrera, Eduardo; Escobar Sánchez, José M.; Montenegro Armas, Rafael; Sarrate Ramos, Josep (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In this paper, we present a new method to insert open surfaces into an existing tetrahedral mesh generated by the meccano method. The surfaces must be totally immersed in the mesh and must not intersect between them. The ...

    The educational programs of Civil Engineering schools have evolved to adapt to changes in society demands and regulations. Specifically, Civil Engineering curricula in Spain was highly impacted by the Bolonia Declaration ...

  • Simulating debris impacts on hydrokinetic infrastructure 

    Aliseda, A; Bagi, A; Johnson, Jerome B; Duvoy, P. X.; Kasper, J. L; Kulchitsky, A; Villardi de Montlaur, Adeline de (2017)
    Comunicació de congrés
    Accés obert
    The discrete element method was applied to model the impact force of woody debris (trees) on hydrokinetic infrastructure in a river setting. The DEM model, termed the Hydrokinetic Debris Impact Simulator (HDIS) was used ...

  • Experimental numerical correlation of subsystem contributions in the advanced transfer path analysis framework 

    Magrans Fontrodona, Francesc Xavier; Arcas, Kevin; Vicens Rodríguez, Pere; Poblet-Puig, Jordi; Rodríguez Ferran, Antonio (2017)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    In a complex vibroacoustic system the overall noise or vibration in a given location is the sum of multiple subsystem contributions. From an experimental perspective, the total noise can be directly measured but not the ...

  • Discrete meso-modeling of steel fiber reinforced concrete: simulation of flexural behavior 

    Pros Parés, Alba; Díez, Pedro; Molins i Borrell, Climent (International Centre for Numerical Methods in Engineering (CIMNE), 2011)
    Text en actes de congrés
    Accés obert
    Concrete provides with a variety of innovative designs, but two characteristics have limited its use: it is brittle and weak under tension. One way to overcome this problem is to add steel fibers into the concrete matrix, ...

  • Combining size-preserving and smoothing procedures for adaptive quadrilateral mesh generation 

    Ruiz Gironés, Eloi; Roca Navarro, Xevi; Sarrate Ramos, Josep (Springer, 2013)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    It is well known that the variations of the element size have to be controlled in order to generate a high-quality mesh. Hence, several techniques have been developed to limit the gradient of the element size. However, the ...

  • Inserting curved boundary layers for viscous flow simulation with high-order tetrahedra 

    Gargallo Peiró, Abel; Roca Navarro, Xevi; Sarrate Ramos, Josep; Peraire Guitart, Jaume (Springer, 2013)
    Comunicació de congrés
    Accés restringit per política de l'editorial
    We propose an a posteriori approach for generating curved meshes for viscous flow simulations composed by high-order tetrahedra. The proposed approach is performed in the following three steps: (1) generate a linear ...
