A discrete element exploration of V-shaped breakout failure mechanisms in underground opening
V-shaped breakouts, which may appear in underground opening during excavation, are the results of two different failure mechanisms: tensile spalling and shear fracturing. This study uses discrete elements in exploring the conditions that would lead to different breakout mechanisms under plane strain...
