  • Alicandro, Roberto; Lazzaroni, Giuliano; Palombaro, Mariapia (2017-01)
    We study continuum limits of discrete models for (possibly heterogeneous) nanowires. The lattice energy includes at least nearest and next-to-nearest neighbour interactions: the latter have the role of penalising changes ...
  • Cagnetti, Filippo; Dal Maso, Gianni; Scardia, Lucia; Zeppieri, Caterina Ida (SISSA, 2017-03-20)
    We study the Gamma-convergence of sequences of free-discontinuity functionals depending on vector-valued functions u which can be discontinuous across hypersurfaces whose shape and location are not known a priori. The main ...
  • Alicandro, Roberto; Dal Maso, Gianni; Lazzaroni, Giuliano; Palombaro, Mariapia (2017-06)
    Linear elasticity can be rigorously derived from finite elasticity under the assumption of small loadings in terms of Gamma-convergence. This was first done in the case of one-well energies with super-quadratic growth and ...
  • Alicandro, Roberto; Lazzaroni, Giuliano; Palombaro, Mariapia (2017-01)
    We analyse the rigidity of non-convex discrete energies where at least nearest and next-to-nearest neighbour interactions are taken into account. Our purpose is to show that interactions beyond nearest neighbours have ...
  • Davoli, Elisa; Mora, Maria Giovanna (SISSA, 2012-04)
    The subject of this paper is the rigorous derivation of a quasistatic evolution model for a linearly elastic - perfectly plastic thin plate. As the thickness of the plate tends to zero, we prove via Gamma-convergence ...
  • Lazzaroni, Giuliano; Palombaro, Mariapia; Schlomerkemper, Anja (SISSA, 2015-01)
    In the context of nanowire heterostructures we perform a discrete to continuum limit of the corresponding free energy by means of Γ-convergence techniques. Nearest neighbours are identified by employing the notions of ...
  • Dal Maso, Gianni; Franzina, Giovanni; Zucco, Davide (2018-03)
    We study the asymptotic behaviour of solutions to variational problems in perforated domains with Neumann boundary conditions. We consider perforations that in the limit concentrate on a smooth manifold. We characterise ...
