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

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).

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).

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.

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.

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
