Paper presented at the Gulf Rocks 2004, the 6th North America Rock Mechanics Symposium (NARMS), June 5–9, 2004
Paper Number: ARMA-04-469
... that the intermediate principal stress does have an impact on rock failure and that this is not adequately captured by the standard Mohr-Coulomb criterion. In response a modified Mohr-Coulomb criterion is established. Furthermore, using a simple example of openhole stability, the study demonstrates...

... special interest, as such tests perhaps most directly reflect the bonding properties of the material. Brazilian and direct tensile tests lead to the conclusion that the intrinsic tensile strength of high porosity chalk is best predicted from the compressional yield criterion (Coulomb). The effect of...

... the case around openings. Thus, a multiaxial criterion that can take into account the 3D nature of rock failure is more appropriate for a realistic determination of in situ stress from borehole breakouts. In this paper, the authors introduce a method to estimate the magnitude of both the maximum and...
