      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
