      Este trabajo se ubica en una perspectiva marcada por dos fuentes de inspiración y exigencia, que se complementan mutuamente: La primera está relacionada con el campo tecnológico y la segunda viene del ambiente científico. ...

    • Fracturing and near-surface diagenesis of a silicified miocene deltaic sequence: the Montjuïc Hill (Barcelona) 

      Cantarero, Irene; Parcerisa Duocastella, David; Plata, Maria Alexandra; Gómez Gras, David Manuel; Gómez Rivas, Enrique; Martín Martín, Juan Diego; Travé, Anna (2020-02-01)
      Article
      Accés obert
      Near-surface diagenesis has been studied in the Langhian siliciclastic rocks of the Montjuïc Hill (Barcelona Plain) by means of petrographical (optical and cathodoluminescence) and geochemical (electron microprobe, d18O, ...

    • Helical crack-front instability in mixed-mode fracture 

      Pons Rivero, Antonio Javier; Karma, Alain (2010-03-04)
      Article
      Accés restringit per política de l'editorial
      [...]We show that the dynamically preferred unstable wavelength is governed by the balance of the destabilizing effect of far-field stresses and the stabilizing effect of cohesive forces on the process zone scale, and we ...
