A rock test cell with true triaxial capability

Geotechnical & Geological Engineering, 1999
Conventional so-called triaxial test cells apply the axial stress to a cylindrical sample using steel platens, with the confining stress developed via an annulus of hydraulic fluid retained by a liner in a pressure cell. This does not allow differentiation between the two principal stresses around the core and inhibits the realism with which the rocks ...

Characterization of Asphalt Concrete by Multi-Stage True Triaxial Testing

Journal of ASTM International, 2005
The feasibility of an existing servo-controlled true triaxial (cubical) apparatus for evaluating the mechanical response of nominal 4-in. cubical specimens of asphalt concrete (AC) under multi-axial stress states has been investigated. The apparatus allows the testing of specimens along a wide range of stress paths and stress levels that are not ...

Development of a True Triaxial Testing Apparatus

Geotechnical Testing Journal, 1992
Abstract 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.

Simulation of triaxial and true triaxial tests on natural and reconstituted Pisa clay

Géotechnique, 2002
A kinematic hardening/bounding surface plasticity model is used to reproduce the experimental behaviour of the natural soft clay found at Pisa. The model accounts for progressive loss of structure with plastic strains, and can be made to degenerate into a structureless state. Model parameters are calibrated on drained triaxial probing tests on natural
