    Conference report
    Open Access
    In recent years, the authors and co-workers have developed a 3D finite element model for coupled thermo-hydro-mechanical (THM) problems in fractured rock masses. Zero-thickness interface elements are used for taking into ...
  • Iterative strategies based on constitutive dissipation 

    Crusat Codina, Laura; Carol, Ignacio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    FE formulation of solid mechanics problems typically require iterative strategies to solve the resulting nonlinear system. Basic strategies with prescribed load values, such as the Newton-Raphson method, are not valid in ...
  • New results in 3D-mesomechanical coupled analysis of external sulphate attack in concrete 

    Biscaro, Caterina; Martínez Estévez, Ariadna; Pérez Carreras, Adrià; López Garello, Carlos María; Xotta, G.; Carol, Ignacio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    External Sulphate Attack (ESA) is one of the main degradation processes affecting concrete structures. It takes place when the concrete is in an environment rich in sulphate ions and with a high humidity index. Once it has ...

    Martínez Estévez, Ariadna; Liaudat, Joaquín; López Garello, Carlos María; Carol, Ignacio (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    In the context of Carbon Capture Storage (CCS) in abandoned hydrocarbon reservoirs, a preliminary study of the effects of pore pressure evolution on the integrity of oil-well cement seals is performed. A 2D cross-section ...
  • Transient large heat advection in fractured rock: a zero-thickness interface formulation 

    Pérez Carreras, Adrià; Carol, Ignacio; Prat Catalán, Pere (International Centre for Numerical Methods in Engineering (CIMNE), 2021)
    Conference report
    Open Access
    In a fractured rock mass, the existence of discontinuities may generate preferential paths where the hydraulic flow velocities are frequently much higher than in the porous medium and heat advection tends to dominate over ...
