    • Analytical micro-modeling of masonry periodic unit cells : elastic properties 

      Drougkas, Anastasios; Roca Fabregat, Pedro; Molins i Borrell, Climent (2015-09-01)
      Article
      Accés obert
      A model for the analysis of masonry periodic unit cells based on detailed micro-modeling principles is presented: an analytical model capable of calculating the orthotropic elastic properties of masonry composites. Several ...

    • Efficient constitutive model for continuous micro-modeling of masonry structures 

      Petracca, Massimo; Camata, Guido; Spacone, Enrico; Pelà, Luca (2023-01)
      Article
      Accés obert
      Masonry is a composite material often modeled as an equivalent homogenous material. However, the complexity of its micro-structure leads to complex mechanical responses, which are almost impossible to capture accurately ...

    • Micro-modeling of stack bond masonry in compression using a plasticity law 

      Drougkas, Anastasios; Molins i Borrell, Climent; Roca Fabregat, Pedro (CIMNE, 2013)
      Text en actes de congrés
      Accés obert
      A set of experimental tests to determine the compressive strength of masonry stack prisms has been numerically simulated using a combined plasticity-smeared crack constitutive law employed in three-dimensional analysis. ...

    • Nonlinear micro-mechanical analysis of masonry periodic unit cells 

      Drougkas, Anastasios; Roca Fabregat, Pedro; Molins i Borrell, Climent (2016-02)
      Article
      Accés obert
      A model for the analysis of masonry periodic unit cells of several wall and pillar geometrical typologies is proposed. It is based on a micro-mechanical analysis of the masonry cell, which has been divided into cuboids, ...

    • Numerical micro-modeling simulation of masonry in compression 

      Drougkas, Anastasios; Roca Fabregat, Pedro; Molins i Borrell, Climent (Universidade do Minho, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Micro-modeling techniques for the simulation of masonry are a valuable tool, when combined with nonlinear constitutive laws, for the investigation of the behavior of structural masonry. Through the simulation of the behavior ...

    • Numerical prediction of the behavior, strength and elasticity of masonry in compression 

      Drougkas, Anastasios; Roca Fabregat, Pedro; Molins i Borrell, Climent (2015-05)
      Article
      Accés obert
      The paper focuses on the numerical prediction of the compressive response of masonry by means of detailed micro-modeling techniques. In such a model, the material constituents (mortar and units) and the unit-mortar interfaces ...

    • Simulation of in-plane shear test on masonry walls using micro modeling tecniques 

      Drougkas, Anastasios; Roca Fabregat, Pedro; Molins i Borrell, Climent (2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      A series of experimental tests involving in-plane shear loading of masonry walls is numerically simulated using finite element detailed micro models. The experimental tests were performed on masonry walls composed of solid ...
