Web1 day ago · Differing from peak stress (σ p), these two stresses σ CI and σ CD are less dependent on the loading condition and considered as the intrinsic properties of rocks (Martin, 1993). The stress corresponding to the fracture initiation is approximately 0.3–0.4σ p, indicating that it is insufficient to use only the σ p to characterize the ...
