    • Cohesive surface model for fracture based on a two-scale formulation: computational implementation aspects 

      Toro, Sebastian; Sánchez, P.J.; Podestá, J.M.; Blanco, P.J.; Huespe, Alfredo Edmundo; Feijóo, R.A. (2016-10)
      Article
      Open Access
      The paper describes the computational aspects and numerical implementation of a two-scale cohesive surface methodology developed for analyzing fracture in heterogeneous materials with complex micro-structures. This approach ...
    • Computational material design for acoustic cloaking 

      Méndez, Carlos Alberto; Podestá, J.M.; Lloberas Valls, Oriol; Toro, Sebastian; Huespe, Alfredo Edmundo; Oliver Olivella, Xavier (John Wiley & Sons, 2017-12)
      Article
      Open Access
      A topology optimization technique based on the topological derivative and the level set function is utilized to design/synthesize the micro-structure of a pentamode material for an acoustic cloaking device. The technique ...
    • Material design of elastic structures using Voronoi cells 

      Podestá, J.M.; Méndez, C. G.; Toro, S.; Huespe, Alfredo Edmundo; Oliver Olivella, Xavier (John Wiley & sons, 2018-07)
      Article
      Open Access
      New tools for the design of metamaterials with periodic microarchitectures are presented. Initially, a two-scale material design approach is adopted. At the structure scale, the material effective properties and their ...
    • Symmetry considerations for topology design in the elastic inverse homogenization problem 

      Podestá, J.M.; Méndez, C. M.; Toro, Sebastian; Huespe, Alfredo Edmundo (2019-07)
      Article
      Open Access
      An analysis of the symmetries characterizing the micro-architecture topologies and the elastic material properties is performed. The goal is to elucidate a systematic procedure that facilitates the design of elastic ...
