On the Applicability of Nadai and Mogi Failure Criteria to Porous Sandstones
Ma, Xiaodong; Ingraham, Mathew D.
Following the ISRM Suggested Method on Failure Criteria, ‘A failure criterion for rocks based on true triaxial testing’ by Chang and Haimson (2012), we attempted to obtain experiment-based Nadai (1950) and Mogi (1971) failure criteria for the aforementioned four sandstones: TCDP (Oku et al. 2007), Coconino, Bentheim (Ma and Haimson 2016; Ma et al. 2017a), and Castlegate (Ingraham et al. 2013). Here, the current work extends beyond the scope of Chang and Haimson (2012), to compare σ1 at failure (i.e., σ1,peak) from test data with predictions based on the experimentally generated Nadai and Mogi criteria. The applicability of Nadai and Mogi criteria to porous sandstones is then evaluated and discussed, considering failure mode evolution in these rocks.
