Effects of intermediate principal stress on rock cavity stability
Journal of Central South University of Technology, 2007The linear Mohr-Coulomb and nonlinear Hoek-Brown failure criteria, which neglect the effects of intermediate principal stress, are widely used in soil and rock engineering. However, much experimental data shows that the failure envelope relates to the intermediate principal stress.

Effect of Intermediate Principal Stress on Overconsolidated Kaolin Clay
Journal of Geotechnical and Geoenvironmental Engineering, 2004The influence of intermediate principal stress on the mechanical behavior of overconsolidated kaolin clay is investigated using three-dimensional true triaxial testing on cubical specimens. A flexible boundary, true triaxial setup with a real-time feedback control system was used to test soil specimens under stress and strain-control modes.

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 ...

Influence of Intermediate Principal Stress Effect on Flat Punch Problems
Key Engineering Materials, 2013Using the finite difference code FLAC3D (Fast Lagrangian Analysis of Continua in 3 Dimensions) and UST (Unified Strength Theory), the influence of the intermediate principal stress effect on the problems of flat punch are analyzed in this paper. The values of the ultimate bearing capacity resulting from numerical analyses and the analytical solution of ...

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.

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).
