  • Adaptive and off-line techniques for non-linear multiscale analysis 

    Zaghi, Stefano; Martínez García, Javier; Rossi, Riccardo; Petracca, Massimo (2018-08-22)
    Article
    Open Access
    This paper presents two procedures, based on the numerical multiscale theory, developed to predict the mechanical non-linear response of composite materials under monotonically increasing loads. Such procedures are designed ...
  • Micro-scale continuous and discrete numerical models for nonlinear analysis of masonry shear walls 

    Petracca, Massimo; Pelà, Luca; Rossi, Riccardo; Zaghi, Stefano; Camata, Guido; Spacone, Enrico (2017-09)
    Article
    Open Access
    A novel damage mechanics-based continuous micro-model for the analysis of masonry-walls is presented and compared with other two well-known discrete micro-models. The discrete micro-models discretize masonry micro-structure ...
  • Multiscale multiphysics simulation in composite materials 

    Zaghi, Stefano (Universitat Politècnica de Catalunya, 2019-01-21)
    Doctoral thesis
    Open Access
    The improvements in terms of computational power provides the capability to analyze with more detail the materials behavior. On one hand, going deeper in the materials to study an increasingly smaller dimension and capture ...
  • Multiscale thermo-mechanical analysis of multi-layered coatings in solar thermal applications 

    Montero-Chacón, Francisco; Zaghi, Stefano; Rossi, Riccardo; García-Pérez, Elena; Heras Pérez, Irene; Martínez García, Javier; Oller Martínez, Sergio Horacio; Doblaré, Manuel (2017-05)
    Article
    Open Access
    Solar selective coatings can be multi-layered materials that optimize the solar absorption while reducing thermal radiation losses, granting the material long-term stability. These layers are deposited on structural materials ...
  • Thermo-mechanical homogenization of composite materials 

    Zaghi, Stefano; Martínez García, Javier; Rossi, Riccardo; Oller Martínez, Sergio Horacio (Asociación Española de Materiales Compuestos, 2015)
