Stress-strain curves and failure modes of the specimen of size 5 × 10 m under different confining pressures. (a) DFN0. (b) DFN30. (c) DFN60. (d) DFN90. (e) DFN120. (f) DFN150. Note that the blue line is the SJM tensile crack, the magenta line is the SJM shear crack, the red line is the FJM tensile crack, and the black line is the FJM shear crack.
