    Accés restringit per política de l'editorial
    We demonstrate a reconfigurable virtual datacenter network by utilizing statistical multiplexing offered by scalable and flow-controlled optical switching system. Results show QoS guarantees by the priority assignment and ...
  • Dimensional hyper-reduction of nonlinear finite element models via empirical cubature 

    Hernández Ortega, Joaquín Alberto; Caicedo Silva, Manuel Alejandro; Ferrer Ferré, Àlex (2017-01)
    Article
    Accés obert
    We present a general framework for the dimensional reduction, in terms of number of degrees of freedom as well as number of integration points (“hyper-reduction”), of nonlinear parameterized finite element (FE) models. The ...
  • Multi-scale topological design of structural materials : an integrated approach 

    Ferrer Ferré, Àlex (Universitat Politècnica de Catalunya, 2017-05-26)
    Tesi
    Accés obert
    The present dissertation aims at addressing multiscale topology optimization problems. For this purpose, the concept of topology derivative in conjunction with the computational homogenization method is considered. In ...

    This book brings together some 20 chapters on state-of-the-art research in the broad field of computational plasticity with applications in civil and mechanical engineering, metal forming processes, geomechanics, nonlinear ...
  • On multi-scale structural topology optimization and material design 

    Ferrer Ferré, Àlex; Cante Terán, Juan Carlos; Oliver Olivella, Xavier (Associação Portuguesa de Mecânica Teórica, Aplicada e Computacional (APMTAC), 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Computational material design has gained considerable interest, along the last years, in the computational mechanics community. Although most of the current approaches focus on one-scale structural optimization, this work ...
  • The domain interface method in non-conforming domain decomposition multifield problemsdomain decomposition multifield problems
