Uniaxial compression results for the specimen of size 5 × 10 m under different loading directions. (a) Stress-strain curves under different loading directions. Note that the blue line is the SJM bond tensile crack, the magenta line is the SJM bond shear crack, the red line is the FJM bond tensile crack, the black line is the FJM bond shear crack, and the gray line is the model boundary. (b) Failure modes under different loading directions.
