... Abstract This paper presents the modeling of rockfalls using the lumped mass method and the DDA method. In the lumped mass method, the block is treated as a lumped mass which neglects the three-dimensional aspects of the block such as the block shape and the subsequent block orientation...

... Abstract This paper aims to take a review on the modeling of damage in quasi-brittle rocks based upon continuum micromechanics. The basic idea of continuum micromechanics is a representation of brittle porous rocks as a material with distributed microcracks. With a crack density parameter...

... Abstract This work focuses on the numerical modeling of coupled thermal, hydraulic and mechanical processes in transverse isotropic rock, with specific consideration of parallel computing aspects. We apply the previously developed parallel finite element scheme to analyze a real application...

... ABSTRACT One of the difficulties in describing the rock mass behavior is assigning the appropriate constitutive model. This limitation may be overcome with the progress in discrete element software such as PFC, which does not need the user to prescribe a constitutive model for rock mass...
