  • Continuum approach to computational multi-scale modeling of fracture 

    Oliver Olivella, Xavier; Caicedo Silva, Manuel Alejandro; Roubin, Emmanuel; Huespe, Alfredo Edmundo (2014-09-01)
    Article
    Open Access
    This paper presents a FE2 multi-scale framework for numerical modeling of the structural failure of heterogeneous quasi-brittle materials. The model is assessed by application to cementitious materials. Using the Continuum ...
  • Continuum approach to computational multiscale modeling of propagating fracture 

    Oliver Olivella, Xavier; Caicedo Silva, Manuel Alejandro; Roubin, Emmanuel; Huespe, Alfredo Edmundo; Hernández Ortega, Joaquín Alberto (2015-09)
    Article
    Open Access
    A new approach to two-scale modeling of propagating fracture, based on computational homogenization (FE2), is presented. The specific features of the approach are: a) a continuum setting for representation of the fracture ...
  • Meso-scale modeling of concrete: a morphological description based on excursion sets of Random Fields 

    Roubin, Emmanuel; Colliat, Jean-Baptiste; Benkemoun, Nathan (2015-05)
    Article
    Open Access
    In view of the significant impact of thin scale heterogeneities in regards with the macroscopic response of concrete (and generally speaking of heterogeneous materials), a particular effort is dedicated to morphological ...
  • Multi-scale (FE2) analysis of material failure in cement/aggregate-type composite structures 

    Oliver Olivella, Xavier; Caicedo, Manuel Alejandro; Roubin, Emmanuel; Hernández Ortega, Joaquín Alberto; Huespe, Alfredo Edmundo (CRC, 2014)
    Conference report
    Open Access
    The work propases a FP multiscale approach to computational modeling of material failure in concreteMlike structures, made of cement/aggregate-type composite materials. Keeping the approach in a classical homogenization ...
  • Reduced order modeling strategies for computational multiscale fracture 

    Oliver Olivella, Xavier; Caicedo Silva, Manuel Alejandro; Huespe, Alfredo Edmundo; Hernández Ortega, Joaquín Alberto; Roubin, Emmanuel (2017-01)
    Article
    Open Access
    The paper proposes some new computational strategies for affordably solving multiscale fracture problems through a FE2 approach. To take into account the mechanical effects induced by fracture at the microstructure level ...
