Effect of Intermediate Principal Stress on the Mechanical Behavior of Angular Sand
Soil Behavior and Geomechanics, 2014 Sand is a naturally occurring, cohesionless, granular material with varying morphology. It has been well studied as a model frictional material, and the strength of the sand ensemble is derived from the inter-granular friction. Facets of sand behaviour, such as the inherent anisotropy and effect of intermediate principal stress, are extremely important

It is important to be fully aware of the dynamic characteristics of saturated soft clays under complex loading conditions in practice. In this paper, a series of undrained tests for soft clay consolidated with different initial major principal stress direction ξ were conducted by a hollow cylinder apparatus (HCA).

Influence of Intermediate Principal Stress on the Bearing Capacity of Strip and Circular Footings
Journal of Engineering Mechanics - ASCE, 2014AbstractStudies of the bearing capacity of footings usually do not take into account the effect of the intermediate principal stress. In practice, the intermediate principal stress has certain influences on the strength of geomaterials (e.g., rock and soil) or concrete.

Canadian Geotechnical Journal, 2010
The measurement and study of the stress–strain–strength behaviour of soils in general stress states involving the change of magnitudes and direction of the principal stresses are necessary and important. To investigate the strength behaviour under such conditions, consolidated undrained tests on remoulded hollow cylinder specimens of completely ...

Effect of intermediate principal stress on the deformation response of sand
Canadian Geotechnical Journal, 1996An experimental investigation of the relevance of the intermediate principal stress (σ2) on the deformation response of a sand is presented. The effects of σ2 are conveniently studied through the nondimensional stress parameter b = (σ2 σ3)/(σ1 σ3).

Experimental Study on Influence of Intermediate Principal Stress on the Permeability of Sandstone
Transport in Porous Media, 2020In engineering, it is considerably important to understand the evolution process of sandstone deformation and permeability under complex stress conditions. Although numerous scholars have reported on sandstone permeability, many of their studies are only based on uniaxial or conventional triaxial stress conditions.

Effects of intermediate principal stress on tensile strength of rocks
International Journal of Fracture, 2013The objective of this study is to experimentally determine the effects of intermediate principal stresses on the tensile strength of rocks. The results are used to assess the predictive capability of the Coulomb criterion when one or more principal stresses are in tension. Four rock types have been tested.
