    • A localized mapped damage model for orthotropic materials 

      Pelà, Luca; Cervera Ruiz, Miguel; Oller Martínez, Sergio Horacio; Chiumenti, Michele (2014-05-08)
      Article
      Accés restringit per política de l'editorial
      This paper presents an implicit orthotropic model based on the Continuum Damage Mechanics isotropic models. A mapping relationship is established between the behaviour of the anisotropic material and that of an isotropic ...

    • An orthotropic damage model for the analysis of masonry structures 

      Pelà, Luca; Cervera Ruiz, Miguel; Roca Fabregat, Pedro (2013)
      Article
      Accés restringit per política de l'editorial
      This paper presents a numerical model for nonlinear analysis of masonry structural elements based on Continuum Damage Mechanics. The material is described at the macro-level, i.e. it is modeled as a homogeneous orthotropic ...

    • Appraisement of planar, bending and twisting cracks in 3D with isotropic and orthotropic damage models 

      Barbat Vlad, Gabriel; Cervera Ruiz, Miguel; Chiumenti, Michele (Springer, 2018-03)
      Article
      Accés obert
      This paper discusses the modeling of cracking in quasi-brittle materials using isotropic and orthotropic damage constitutive laws. A mixed strain/displacement finite element formulation is used, taking advantage of its ...

    • Architecture of a multi-crack model with full closing, reopening and sliding capabilities 

      Cervera Ruiz, Miguel; Barbat Vlad, Gabriel; Chiumenti, Michele (Springer, 2020-06)
      Article
      Accés obert
      This paper discusses the finite element modeling of cracking of quasi-brittle materials under cyclic loading. A damage based crack model is proposed, which considers tensile and compressive damage, irreversible strains ...

    • Continuum damage model for nonlinear analysis of masonry structures 

      Pelà, Luca (Universitat Politècnica de Catalunya, 2009-03-26)
      Tesi
      Accés obert
      The present work focuses on the formulation of a Continuum Damage Mechanics model for nonlinear analysis of masonry structural elements. The material is studied at the macro-level, i.e. it is modelled as a homogeneous ...

    • Mechanism-Based damage and failure of Fused Filament Fabrication components 

      Rivet Fernández, Iván; Dialamishabankareh, Narges; Cervera Ruiz, Miguel; Chiumenti, Michele (Elsevier, 2024-02)
      Article
      Accés restringit per política de l'editorial
      Fused Filament Fabrication (FFF) is a polymer-based Additive Manufacturing (AM) technology that produces complex layered components. The characterization of the inherited orthotropic properties of FFF components and their ...
