    • 3D analysis of H-M coupled problem with zero-thickness interface elements applied to geomechanics 

      Garolera Vinent, Daniel; Segura Serra, Josep Maria; Carol, Ignacio; Lakashmikhanta, Ramasesha; Alvarellos, J. (CIMNE, 2015)
      Conference lecture
      Open Access
      In spite of the significant developments seen in recent years,numerical modelin of Hydraulic Fracturing still poses major challenges due to the strong coupling between fluid flow and crack development,which is itself a ...

    • Boundary effects in the desiccation of soil layers with controlled environmental conditions 

      Lakashmikhanta, Ramasesha; Prat Catalán, Pere; Ledesma Villalba, Alberto (2018-07)
      Article
      Open Access
      This article presents the results of an experimental research carried to investigate the mechanics of cracking of soil layers under drying conditions. The tests were conducted under controlled laboratory conditions and in ...

    • 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)

      An accurate description of the in-situ stress field in a rock mass is crucial in different areas of geo-engineering such as: underground excavations, hydrocarbon extraction, CO2 storage, hydraulic fracture etc. In this ...

    • Numerical modelling of the wedge splitting test in rock specimens, using fracture-based zero-thickness interface elements 

      Liaudat, Joaquín; Garolera Vinent, Daniel; Martínez Benasat, Antonio; Carol, Ignacio; Lakashmikhanta, Ramasesha; Alvarellos, J. (CIMNE, 2015)
      Conference lecture
      Open Access
      The purpose of the Wedge Splitting Test (WST) is to generate stable mode I fracture crack along a pre-established path, and be able to measure the specific fracture energy parameter of the material GFI. The test is performed ...

    • Numerical stress initialization in geomechanics via the FEM and a two-step procedure 

      Aliguer Piferrer, Ignasi; Carol, Ignacio; Prat Catalán, Pere; Rafels Ybern, Carles; Lakashmikhanta, Ramasesha; Segura Serra, Josep Maria (CIMNE, 2015)
      Conference lecture
      Open Access
      The knowledge of the in-situ stress field in rock masses is crucial in different areas of geo-engineering, such as mining or civil underground excavations, hydrocarbon extraction, CO2 storage, hydraulic fracture operations, ...
