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)
Comunicació de congrés
Accés obertIn 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 ... -
Avoiding fracture instability in wedge splitting tests by means of numerical simulations
Liaudat, Joaquín; Garolera, D.; Martínez, A.; Carol, Ignacio; Lakshmikantha, M.R.; Alvarellos, J. (CIMNE, 2017)
Text en actes de congrés
Accés obertIn this paper, unstable fracture propagation obtained in a in-house performed experimental Wedge Splitting Test (WST) is simulated by means of the FEM and fracturebased zero-thickness interface elements. In order to obtain ... -
Coupled h-m fracture interaction using fem with zero-thickness interface elements
Garolera Vinent, Daniel; Segura, J. M.; Carol, Ignacio; Lakshmikantha, M.R.; Alvarellos, J. (CIMNE, 2017)
Text en actes de congrés
Accés obertIntensive hydraulic fracturing is a procedure employed for low permeability reservoir stimulation. This technique consists of generating a sequence of regularly spaced parallel fractures (multi-stage fracturing). The ... -

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)
Comunicació de congrés
Accés obertThe 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 ... -
Zero-thickness interface elements with h-m coupling, formulation and applications in geomechanics
Garolera Vinent, Daniel; Aliguer Piferrer, Ignasi; Segura, J. M.; Carol, Ignacio; Lakshmikantha, M. R.; Alvarellos, J. (CIMNE, 2013)
Text en actes de congrés
Accés obertPrevious developments on zero-thickness interface elements for coupled Hydro-Mechanics problems are briefly described, followed by some new geomechanical applications, particularly to hydraulic fracture in rock. The results ...
