Abstract
In the axisymmetric compression test, rock samples, even those which are isotropic when unstressed, develop a transversely isotropic structure after a small amount of inelastic deformation due to the preferential growth of microcracks in the axial direction. To examine the effect of this developed anisotropy on faulting, conditions for the localization of deformation are derived for the most general form of stress strain relation for a material exhibiting transversely isotropic incremental response. This constitutive law involves six indepenent, incremental moduli. Expressions are derived for the predicted slope of the axial stress vs. axial strain curve at faulting and for the predicted fracture angle.
