Effect of intermediate principal stress on strength of soft rock under complex stress states
Journal of Central South University, 2014A series of numerical simulations of conventional and true triaxial tests for soft rock materials using the three-dimensional finite difference code FLAC3D were presented. A hexahedral element and a strain hardening/softening constitutive model based on the unified strength theory (UST) were used to simulate both the consolidated-undrained (CU ...

Effect of the intermediate principal stress on rock failure
Journal of Geophysical Research, 1967Precise testing methods have been applied to an experimental study of the effect of the intermediate principal stress σ2 on failure of a granite, a limestone, and a dolomite rock at room temperature. σ2 affects failure in two ways. Strength at failure increases with σ2 by an amount that is proportional to, although smaller than, the amount of the least

Effect of the intermediate principal stress on 3-D crack growth
Engineering Fracture Mechanics, 2018Abstract An experimental and numerical investigation of 3-D crack growth in biaxial compression is presented. We tested a series of transparent casting resin samples, each with a single initial penny-shape crack at the sample centre. We applied biaxial compression with different ratios ( σ x / σ y ) between the lateral (the intermediate

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).

Effect of intermediate principal stress on strength of anisotropic rock mass
Tunnelling and Underground Space Technology, 1998Abstract The Mohr-Coulomb criterion needs to be modified for highly anisotropic rock material and jointed rock masses. Taking σ2 into account, a new strength criterion is suggested because both σ2 and σ3 would contribute to the normal stress on the existing plane of weakness.

Effects of Cyclic Intermediate Principal Stress on the Deformation of Saturated Clay
Journal of Geotechnical and Geoenvironmental Engineering, 2018AbstractOne-way cyclic loading induced by traffic loads will give rise to the cyclic variation of normal stress components of all three directions, including one vertical and two horizontal ones.

Effect of Intermediate Principal-Stress Ratio on Particle Breakage of Rockfill Material
Journal of Geotechnical and Geoenvironmental Engineering, 2016AbstractThe true triaxial compression test is the three-dimensional test, where the intermediate principal stress is not less than the minor principal stress and not more than the major principal stress. The effect of the intermediate principal stress ratio (i.e., the b-value) on particle breakage of rockfill material (RFM) was investigated by ...
