“…2b (Meyer and Labuz 2012). Various researchers (Mogi 1971(Mogi , 1974Takahashi and Koide 1989;Chang and Haimson 2000;Al-Ajmi and Zimmerman 2005) have performed true triaxial testing, and the intermediate stress effect appears to depend on rock type, although anisotropy and experimental conditions may also influence the results. In fact, anisotropy can cause a reserve intermediate-stress effect, where the friction angle appears larger in compression than extension (Dehler and Labuz 2007).…”

“…In this paper, it is assumed that the creep failure of rocks is due to the presence of penny-shaped microcracks and there is abundant evidence for the existence of microcracks in rocks [13][14]. Therefore, this model is physically plausible and the following assumptions are made: (i) penny-shaped microcracks are assumed to be randomly distributed in Burgers viscoelastic rock matrix; (ii) the interaction between penny-shaped microcracks is neglected before the coalescence of microcracks.…”

“…25). Moreover, Al-Ajmi and Zimmerman (2005) showed that for an axisymmetric state of stresses (σ 2 = σ 3 ), the linear Mogi criterion (11) reduces to the Coulomb criterion (2) or (3) with parameters a and b equal, respectively, to: …”
