  • A phase-field/gradient damage model for brittle fracture in elastic-plastic solids 

    Duda, Fernando P.; Ciarbonetti, A.; Sánchez, P.J.; Huespe, Alfredo Edmundo (2015-02)
    Article
    Open Access
    The formulation of a phase-field continuum theory for brittle fracture in elastic-plastic solids and its computational implementation are presented in this contribution. The theory is based on a virtual-power formulation ...
  • Crack-path field and strain-injection techniques in computational modeling of propagating material failure 

    Oliver Olivella, Xavier; Dias, I.F.; Huespe, Alfredo Edmundo (2014-01)
    Article
    Open Access
    The work presents two new numerical techniques devised for modeling propagating material failure, i.e. cracks in fracture mechanics or slip-lines in soil mechanics. The first one is termed crack-path-field technique and ...
  • Experimental observations of two-phase flow in rough-walled fractures 

    Salvador Roda, Clara (Universitat Politècnica de Catalunya, 2014-06-06)
    Master thesis (pre-Bologna period)
    Open Access
    This thesis presents an experimental investigation about the concurrent ow of water-air in a rough walled fracture. The focus of this investigation is on studying the effects of varying the orientation or gravity factor ...
  • Extraction of a crack opening from a continuous approach using regularized damage models 

    Dufour, F.; Pijaudier-Cabot, Gilles; Choinska, M; Huerta, Antonio (2008-11)
    Article
    Restricted access - publisher's policy
    Crack opening governs many transfer properties that play a pivotal role in durability analyses. Instead of trying to combine continuum and discrete models in computational analyses, it would be attractive to derive from ...
  • Phase-field modeling and simulation of fracture in brittle materials with strongly anisotropic surface energy 

    Li, Bin; Peco, Christian; Millán, Daniel; Arias Vicente, Irene; Arroyo Balaguer, Marino (John Wiley & Sons, 2015-04-20)
    Article
    Restricted access - publisher's policy
    Crack propagation in brittle materials with anisotropic surface energy is important in applications involving single crystals, extruded polymers, or geological and organic materials. Furthermore, when this anisotropy is ...
  • Strain localization and failure mechanics for elastoplastic damage solids 

    Wu, Jian-Ying; Cervera Ruiz, Miguel (Centre Internacional de Mètodes Numèrics en Enginyeria (CIMNE), 2014)
    Book
    Restricted access - publisher's policy
    This work investigates systematically strain localization and failure mechanics for elastoplastic damage solids. Two complementary methodologies, i.e., traction-based discontinuities localized in an elastic solid and strain ...
