Abstract:
The majority of the studies to understand the complex problem of stress redistribution in rocks have considered rock as an isotropic material. However, rock in nature is never isotropic. Rocks need to be considered as an anisotropic material to get more accurate information about stress redistribution. Earlier analytical and numerical modelling studies were conducted to study the effect of peak stress on bedding planes. In addition to this effect, the current study discusses the effect of rock anisotropy on the stress redistribution. The modelling was done using the numerical code, Particle Flow Code in 3-Dimensions (PFC3D). The results matched with both analytic and numerical modelling studies.
