L'activitat científica general del grup es el desenvolupament de mètodes de la mecànica computacional per a la modelització de problemes a l'Enginyeria. Dins d'aquest context, el grup treballa més específicament en les següents àrees:
a) Modelització numèrica de processos de fabricació industrial.
b) Modelització numèrica del comportament mecànic de materials i estructures.
c) Eines avançades per al disseny computacional de materials d'enginyeria.

    Article
    Accés restringit per política de l'editorial
    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 ...
  • The concept of Representative Volume Elements for elastic, hardening and softening materials

    Text en actes de congrés
    Accés restringit per política de l'editorial
    The concept of the Representative Volume Element (RVE) is analysed in the present paper. For elastic materials, one can determine the size of the RVE. However, for other applications, such as the case of softening materials, ...

    Text en actes de congrés
    Accés obert
    The multiscale framework presented in [1, 2] is assessed in this contribution for a study of random heterogeneous materials. Results are compared to direct numerical simulations (DNS) and the sensitivity to user-defined ...
  • Concurrent multiscale analysis of heterogeneous materials 

    Lloberas Valls, Oriol; Everdij, Frank P. X.; Rixen, Daniel J.; Simone, Angelo; Sluys, Lambertus J. (Vienna University of Technology, 2012)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Concurrent multiscale analysis of quasi-brittle heterogeneous materials such as concrete and rock is conducted employing non-overlapping domain decomposition techniques. Initially, a coarse discretization with effective ...
