2020-6-1  For granite, the fracture dip angles of the specimens are greater than 80° where σ 2 ≥ 50 MPa at σ 3 = 10 MPa, σ 2 ≥ 150 MPa at σ 3 = 20 MPa, and σ 2 ≥ 300 MPa at σ 3 = 30 MPa. Under these stress conditions, the fracture orientations in the granite specimens are distributed approximately along the σ 1 σ 2 plane, which is similar to slabbing failure.
