    • 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 ...

      Rafels Ybern, Carles (Universitat Politècnica de Catalunya, 2016-10-19)
      Master thesis
      Open Access
      Tradicionalment, els reservoris d'Oil i Gas (O&G) s'han modelitzat des del punt de vista dels fluids en un medi porós d'esquelet sòlid indeformable i infinitament resistent. En temps recents però, s'està fent palès que ...
