      Modeling of big faults or weak planes of strong and weak discontinuities is of major importance to assess the Geomechanical behaviour of mining/civil tunnel, reservoirs etc. For modelling fractures in Geomechanics, prior ...

    • Further developments in stress initialization in geomechanics via FEM and a two-step procedure involving Airy functions 

      Rafels Ybern, Carles; Jaqués Adell, Irene; Aliguer Piferrer, Ignasi; Carol, Ignacio; Prat Catalán, Pere; Lakshmikantha, Ramasesha Mookanahallipatna; Segura Segarra, José María (2017)
      Conference report
      Open Access
      The in-situ stress field in rock masses is a key aspect when a numerical analysis of a rock mass is carried out in any area of geo-engineering, such as civil, mining, or Oil & Gas. A method for the numerical generation of ...

    • Methods for FEM stress initialization based on stress functions, and application to a reservoir cross-section 

      Aliguer Piferrer, Ignasi; Rafels Ybern, Carles; Jaqués Adell, Irene; Carol, Ignacio; Prat Catalán, Pere; Lakashmikhanta, Ramasesha; Segura Segarra, José María (OnePetro, 2013)
