    • A computational multiscale homogenization framework accounting for inertial effects: application to acoustic metamaterials modelling 

      Roca Cazorla, David; Lloberas Valls, Oriol; Cante Terán, Juan Carlos; Oliver Olivella, Xavier (2018-03)
      Article
      Open Access
      A framework, based on an extended Hill–Mandel principle accounting for inertial effects (Multiscale Virtual Work principle), is developed for application to acoustic problems in the context of metamaterials modelling. The ...
    • Computational design of locally resonant acoustic metamaterials 

      Roca Cazorla, David; Yago Llamas, Daniel; Cante Terán, Juan Carlos; Lloberas Valls, Oriol; Oliver Olivella, Xavier (2019-03)
      Article
      Restricted access - publisher's policy
      The so-called Locally Resonant Acoustic Metamaterials (LRAM) are considered for the design of specifically engineered devices capable of stopping waves from propagating in certain frequency regions (bandgaps), this making ...
    • Experimental and numerical assessment of local resonance phenomena in 3D-printed acoustic metamaterials 

      Roca Cazorla, David; Pàmies Gómez, Teresa; Cante Terán, Juan Carlos; Lloberas Valls, Oriol; Oliver Olivella, Xavier (2020-04)

      The so called Locally Resonant Acoustic Metamaterials (LRAM) are a new kind of artificially engineered materials capable of attenuating acoustic waves. As the name suggests, this phenomenon occurs in the vicinity of internal ...
    • Numerical tools for computational design of acoustic metamaterials 

      Roca Cazorla, David (Universitat Politècnica de Catalunya, 2020-09-07)
      Doctoral thesis
      Open Access
      The notion of metamaterials as artificially engineered structures designed to obtain specific material properties, typically unachievable in naturally occurring materials, has captured the attention of the scientific and ...
