Proceedings Papers

Paper presented at the 49th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2015
Paper Number: ARMA-2015-366
... Abstract A grain-based rock model was developed and applied to study wellbore stability. The rock is represented as an assembly of tetrahedral blocks with bonded contacts. Material heterogeneity is modeled by varying the tensile strength at the block contacts. This grain-based rock model...

Paper presented at the 48th U.S. Rock Mechanics/Geomechanics Symposium, June 1–4, 2014
Paper Number: ARMA-2014-7660
... Abstract This paper describes how 3DEC can be used to model rock as an assembly of tetrahedral (tet) blocks bonded at their contacts and how this can be used to study veined rock masses at a large scale by introducing tensile strength heterogeneity at the block contacts. The 3 DEC approach...
