    • 3D numerical model of a confined fracture tests in concrete 

      Montenegro, Oscar Ivan; Sfer, Domingo; López Garello, Carlos María; Carol, Ignacio (2013)
      Text en actes de congrés
      Accés obert
      The paper deals with the numerical simulation of a confined fracture test in concrete. The test is part of the experimental work carried out at ETSECCPB-UPC in order to elucidate the existence of a second mode of fracture ...

    • An accurate nonlocal bonded discrete element method for nonlinear analysis of solids: application to concrete fracture tests 

      Celigueta Jordana, Miguel Ángel; Latorre Sánchez, Juan Salvador; Arrufat Garcia, Ferran; Oñate Ibáñez de Navarra, Eugenio (Springer, 2020-05)
      Article
      Accés obert
      We present a numerical procedure for elastic and nonlinear analysis (including fracture situations) of solid materials and structures using the discrete element method. It can be applied to strongly cohesive frictional ...

    • Análisis 2D y 3D de la fractura del hormigón por ataque sulfático externo 

      López Garello, Carlos María; Vélez, A.; Carol, Ignacio; Pérez Carreras, Adrià; Idiart, Andrés (Grupo Español de Fractura, 2019)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      El hormigón puede degradarse debido a diferentes formas de ataques químicos. Este artículo se centra en uno de ellos, el ataque sulfático externo. Un modelo de difusión-reacción se ha combinado en un contexto acoplado a ...

    • Determination of the energy release rate function for an eccentrically notched center-loaded beam using elastic fracture analysis 

      García Álvarez, Víctor Óscar; Gettu, Ravindra; Carol, Ignacio (2017-04)
      Article
      Accés restringit per política de l'editorial
      The center-loaded beam with an eccentric notch is a simple test setup for studying non-planar fracture, which is a common cracking mode in structural elements. This work presents a methodology for obtaining the relations ...
