Rock masses in nature contain numerous discontinuities as cracks, joints, cleavages, beddings and even faults etc. In the cracked material, the stress intensity factors (SIFs) at crack tips, which govern the crack propagation and are associated with the strength of the material, are strongly affected by crack inclination angle, orientation of anisotropy. This book presents the development of a unified numerical framework based on the BEM for modeling crack propagation behavior in anisotropic rocks. The following topics are discussed in this book: 1. Evaluating the SIFs －A new...
