    • Discrete meso-modeling of steel fiber reinforced concrete: simulation of flexural behavior 

      Pros Parés, Alba; Díez, Pedro; Molins i Borrell, Climent (International Centre for Numerical Methods in Engineering (CIMNE), 2011)
      Conference report
      Open Access
      Concrete provides with a variety of innovative designs, but two characteristics have limited its use: it is brittle and weak under tension. One way to overcome this problem is to add steel fibers into the concrete matrix, ...
    • Model validation for the numerical simulation of the Double Punch Test 

      Pros Parés, Alba; Díez, Pedro; Molins i Borrell, Climent (2008)
      Conference report
      Open Access
      The Double Punch test, an indirect traction test, is simulated numerically considering two different models (the nonlocal Mazars damage model and an heuristic crack model with joint elements). The test was designed to ...
    • Modeling steel fiber reinforced concrete: numerical immersed boundary approach and a phenomenological mesomodel for concrete-fiber interaction 

      Pros Parés, Alba; Díez, Pedro; Molins i Borrell, Climent (John Wiley & Sons, 2012-04)
      Article
      Open Access
      Steel fiber reinforced concrete (SFRC) allows overcoming brittleness and weakness under tension, the main drawbacks of plain concrete. The influence of the fibers on the behavior of SFRC depends on their shape, length, ...
    • Numerical approach for modeling steel fiber reinforced concrete 

      Pros Parés, Alba (Universitat Politècnica de Catalunya, 2012-02-06)
      Doctoral thesis
      Open Access
      One alternative to overcome the main drawbacks of plain concrete in tension (its brittleness and weakness) is Steel Fiber Reinforced Concrete (SFRC), a technique introduced in the 70's, which consists of adding steel fibers ...
    • Numerical modeling of the double punch test for plain concrete 

      Pros Parés, Alba; Díez, Pedro; Molins i Borrell, Climent (2011-04)
      Article
      Open Access
      Double punch test is used to indirectly assess the tensile strength of plain concrete, ft. For this normalized test, the tensile strength is obtained as a function of the failure load, P, which is expressed as f_t = F(P). ...
    • Numerical tool for modeling steel fiber reinforced concrete 

      Molins i Borrell, Climent; Pros Parés, Alba; Díez, Pedro (International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM), 2012)
      Conference report

      Steel Fiber Reinforced Concrete (SFRC) allows overcoming brittleness and weakness in tension, the main drawbacks of plain concrete. The goal of the present presentation is to present an ad-hoc numerical strategy to account ...
    • Simulació numèrica d’assaigs de tracció indirecta pel formigó en massa 

      Pros Parés, Alba (Universitat Politècnica de Catalunya, 2008-02)
      Master thesis
      Open Access
      El que pretén aquest projecte, doncs, és fer la simulació numèrica de l’assaig de doble punxonament pel cas de formigó en massa. De la mateixa manera, també es farà la simulació d’un altre assaig de tracció indirecta: l’assaig ...
    • Simulación numérica del hormigón reforzado con fibras de acero 

      Pros Parés, Alba; Díez, Pedro; Molins i Borrell, Climent (Asociacion Científica del Hormigón Estructural (ACHE), 2011)
      Conference report
      Restricted access - publisher's policy
      El Hormigón Reforzado con Fibras de Acero (HRFA) es una técnica que consiste en añadir fibras de acero en el hormigón. La forma, las dimensiones, la esbeltez, la orientación y la distribución de las fibras caracterizan el ...
