    Fernandino, D.O.; Cisilino, A. P.; Toro, S.; P.J., Sánchez (Springer, 2017-09)
    Article
    Open Access
    A multi-scale analysis of the linear elastic and the early damage stages of ferritic ductile iron is introduced in this work. The methodology combines numerical and experimental analyses in the macro and micro scales. ...
  • Optimization-based design of a heat flux concentrator 

    Peralta, Ignacio; Fachinotti, Víctor D.; Ciarbonetti, Ángel A. (Nature Publishing Group, 2017)
    Article
    Open Access
    To gain control over the diffusive heat flux in a given domain, one needs to engineer a thermal metamaterial with a specific distribution of the generally anisotropic thermal conductivity throughout the domain. Until now, ...
