Effect of Intermediate Principal Stress on the Strength, Deformation, and Permeability of Sandstone [PDF]
Energies, 2018 Although the mechanical behaviors and flow aspects of sandstone have been previously investigated, studies of the effect of the intermediate principal stress (σ2) on the strength, deformation, and permeability of sandstone are lacking. In this work,

Failure criterion for soft rocks considering intermediate principal stress
International Journal of Mining Science and Technology, 2021 The significant differences between hard rocks (more brittle) and soft rocks (more ductile) may suggest the use of different failure criteria. A strength criterion for soft rocks that includes intermediate principal stress was proposed. The new criterion

Effect of intermediate principal stress on the stability of slopes [PDF]
Archives of Civil EngineeringThe intermediate principal stress (σ2 ) effect is a mechanical property inherent in many rock and soil materials. However, the effect of σ2 is often ignored in slope stability analyses, and its impact on slope stability is seldom investigated.

Impact of the intermediate principal stress on the strength of heterogeneous rock [PDF]
Journal of Geophysical Research, 2002 A numerical model simulating a granular material has been used to study the impact of the intermediate principal stress on rock strength. While maintaining the minimum principal stress at zero, the model predicts strength to increase with increasing constant ratios of σ2/σ1.

Influence of orientation of the intermediate principal stress on fracture reactivation in granite
Journal of Rock Mechanics and Geotechnical EngineeringFracture (fault) reactivation can lead to dynamic geological hazards including earthquakes, rock collapses, landslides, and rock bursts. True triaxial compression tests were conducted to analyze the fracture reactivation process under two different ...
