    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 ...

    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, ...
