1 International Journal of Rock Mechanics and Mining Sciences Analysis of geo-structural defects in flexural toppling failure Abbas Majdi and Mehdi Amini Abstract The in-situ rock structural weaknesses, referred to herein as geo-structural defects, such as naturally induced micro-cracks, are extremely responsive to tensile stresses. Flexural toppling failure occurs by tensile stress caused
