    • Reactive transport modeling of leaking CO2-saturated brine along a fractured pathway 

      Ahmad, Nawaz; Worman, Anders; Bottaccin Busolin, Andrea; Sánchez Vila, Francisco Javier (John Gale, 2015-11)
      Article
      Accés obert
      One concern regarding the underground storage of carbon dioxide (CO2) is its potential leakage from reservoirs. Over short period of time, the leakage risk is related mainly to CO2 as a separate supercritical fluid phase. ...

    • Shear design of reinforced and prestressed concrete beams based on a mechanical model 

      Marí Bernat, Antonio Ricardo; Bairán García, Jesús Miguel; Cladera Bohigas, Antoni (International Federation for Structural Concrete (fib), 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Different resisting actions interact in the shear resistance of cracked concrete beams whose relative importance varies along loading as damage evolves. Thus, it is not possible to establish a governing resisting action ...

    • Simulations of fracture in concrete beams under bending using a continuum and discrete approach 

      Nitka, M.; Skarzynski, L.; Tejchman, J. (CIMNE, 2015)
      Comunicació de congrés
      Accés obert
      The paper describes two-dimensional meso-scale results of fracture in notched concrete beams under bending. Concrete was modelled as a random heterogeneous 4-phase material composed of aggregate particles, cement matrix, ...

    • The fracture testing of ductile polymer films: Effect of the specimen notching 

      León Albiter, Noel; Martínez Benasat, Antonio; Castejón, P.; Arencón Osuna, David; Martínez, P. P. (Elsevier, 2017-10-01)
      Article
      Accés obert
      The fracture of a ductile polymer film, a heterophase ethylene-propylene block copolymer, has been studied, combining a range of characterisation methods in an attempt to provide a better understanding of the intricate ...

    • Three-dimensional simulation of crack propagation in ferroelectric polycrystals: Effect of combined toughening mechanisms 

      Abdollahi Hosnijeh, Amir; Arias Vicente, Irene (2014-02-15)
      Article
      Accés restringit per política de l'editorial
      We simulate the fracture processes of ferroelectric polycrystals in three dimensions using a phase-field model. In this model, the grain boundaries, cracks and ferroelectric domain walls are represented in a diffuse way ...
