Plots showing FBCM-generated shear fractures from triaxial compression testing of 54-mm diameter cylindrical specimens of previously unfractured rock, with constant horizontal pressure (indicated atop each plot). Each plot shows a vertical section through the center of the specimen. Dip angles for selected fracture zones are also illustrated.

Each plot shows the zones of fractured rock. The exterior outline of the specimen disc is shown, but unfractured rock is excluded from the plots (except for a rectangular plate at each disc end) to facilitate visualization of the fracture zones. Blue indicates unfractured rock; orange, rock with a single tensile fracture; green, rock with a single shear fracture; and red, rock with two fractures (one tensile and one shear). All plots show a vertical tensile fracture that initiated at the interior and propagated to the cylindrical surface. Plot (D) also shows fractures that initiated at the cylindrical surface.
