Post Failure Behaviour of a Rock Mass Under the Influence of Triaxial and True Triaxial Confinement
Engineering Geology, 2006In this paper results of triaxial and true triaxial testing conducted on physical models of a rock mass are used to describe its post failure behaviour. The specimens comprised of three continuous joint sets and were prepared from blocks of sand lime model material.

True Triaxial Testing of Anisotropic Solids
56th U.S. Rock Mechanics/Geomechanics Symposium, 2022ABSTRACT: Accurate determination of rock mechanical properties (particularly sedimentary shales, mica and schists with foliation and bedding planes) is critical to the safe design and excavation of underground mines and tunnels.

Triaxial and True Triaxial Testing of Preserved and Partially Saturated Shale
Proceedings, 2016Samples of a clay-rich shale have been subjected to standard and true triaxial stress conditions to investigate the impact of the intermediate principal stress on shale strength and elastic stiffness. In addition, samples were immersed in different relative humidity environments to evaluate the impact of changing water saturation on rock properties ...

Development of a True Triaxial Testing Apparatus
Geotechnical Testing Journal, 1992Abstract A stress-controlled, flexible boundary, true (or cubical) triaxial apparatus has been developed to investigate the behavior of cemented sand under various stress paths which are not achievable using conventional axisymmetric triaxial apparatus.

1988
Results of both drained and undrained triaxial tests performed with a true triaxial cell on both natural and artificial clays are presented and discussed. The true triaxial apparatus, which has been used for about 20 years, is fully described. The apparatus has recently been modified to improve the measurement of lateral deformations.

The Cambridge True Triaxial Apparatus
1988In true triaxial apparatus, samples of soil are subjected to three independent principal stresses and strains. Such apparatus can readily be used for controlled exploration of principal stress or principal strain space to provide information concerning the anisotropic response of the soil to aid the development of constitutive relations.

True Triaxial Yielding and Hardening of Rock
Journal of Geotechnical Engineering, 1987Analysis of test results for intact and granulated marbles (cemented and noncemented granular materials) adds to the indications that strain softening does not express a real material behavior; it highlights similarities in stressstrain relations and confirms equality of a stress and a plastic strain invariant. The physical meaning of the parameters of

Analysis of Shear Banding in True Triaxial Tests on Sand
Journal of Engineering Mechanics, 2001A series of true triaxial tests have been performed on rectangular prismatic specimens of Santa Monica Beach sand at three different relative densities to study the occurrence of failure, mechanism...

On the determination of true stress triaxiality in sheet metal
Journal of Materials Processing Technology, 2007Abstract Material ductility, or the failure strain, is generally characterized by simple tensile tests. However, tensile tests on sheet samples lead to higher strain gradients than those observed in axisymmetric samples, so the classical Bridgeman correction is invalid.

True Triaxial Apparatuses with Two Rigid Boundaries
Site Characterization and Modeling, 2005A small-scale and a large-scale true triaxial apparatuses (where σ1≠σ2≠σ3) were recently developed at the Institute of Industrial Science, University of Tokyo, Japan and are described in this paper. In these apparatuses, a comprehensive loading system that can control both strain rate and stress rate is used for the vertical (axial) direction.
