Zero-thickness joint/interface elements of the Goodman type, have been advantageously used to solve many problems in solid mechanics involving material interfaces or discontinuities. Some years ago, the authors have also proposed a version of such element for flow/diffusion and hydro-mechanical (H-M) coupled problems, either geomechanical or multiphysics. Some advantages are for instance that f...

Fractures such as faults and joints often dominate the mechanical strength deformation of rock masses. It is thus central importance to adopt an appropriate joint constitutive model in geomechanics simulations so that behaviour fractures can be realistically represented. Over past decades, various models have been proposed from theoretical/experimental perspectives implemented into different so...

Particle finite element method (PFEM) is an effective numerical tool for solving large-deformation problems in geomechanics. By incorporating the node integration technique with strain smoothing into PFEM, we proposed smoothed particle (SPFEM). This paper extends SPFEM to three-dimensional cases and presents a executed on graphics processing units (GPUs) boost computational efficiency. The deta...
