Schematic of joints and initial stress distribution. (Red lines indicate joints. The specimens have a width of 50 mm and a height of 100 mm. The initial confining stress is 1 MPa.) (a) Persistent joints; (b) nonpersistent joints; (c) initial stress distribution for the persistent joints; (d) initial stress distribution for the nonpersistent joints.
