Paper presented at the 49th U.S. Rock Mechanics/Geomechanics Symposium, June 28–July 1, 2015
Paper Number: ARMA-2015-487
... of pre-existing flaws. In this study, numerical simulations of a single oriented flaw in brittle rock materials in uniaxial compression were carried out using the extended finite element method (XFEM) and the displacement discontinuity method (DDM). The code FROCK was used for DDM simulations and the...

Paper presented at the DC Rocks 2001, The 38th U.S. Symposium on Rock Mechanics (USRMS), July 7–10, 2001
Paper Number: ARMA-01-0731
... cracks are shear cracks that also initiate from the tips of the flaws and propagate in a stable manner. Numerical simulations with the code FROCK, a Hybridized Indirect Boundary Element Method, show that: (1) the initiation of a kink does not eliminate the stressingularity at the tip of the flaw; (2) the...
