Failure of Castlegate Sandstone Under True Triaxial Loading

2011
A test series designed to investigate and quantify the effect of the intermediate principal stress on the failure of Castlegate sandstone was completed. Using parallelepiped specimens and a true triaxial testing system, constant mean stress tests were conducted. Stress states ranged from axisymmetric compression to axisymmetric extension.

A Small True Triaxial Apparatus with Wave Velocity Measurement

Geotechnical Testing Journal, 2005
Abstract This paper describes a new cubical, true triaxial apparatus recently developed at the University of Western Australia (UWA). The apparatus is a stand-alone unit of the rigid type, where three pairs of pistons can be pressurized to impose three independent, rectilinear stresses on a sample of 250 mm side length. The sample can be

A True Triaxial Cell for Soil and Rock

1988
The design and performance of a membrane-piston, high-pressure (σ2 − σ3 ≦ 300 MN/m2) cell are presented. This device is similar to the one used for standard triaxial tests differing only in the stresses, σ2 and σ3, which are independently applied through flexible polyvinyl chloride (PVC) fluid cushions on prismatic specimens.

Reducing boundary effects during True Triaxial loading of rocks

Even though stresses in the crust are triaxial (𝜎1>𝜎2>𝜎3) the overwhelming majority of rock deformation experiments are conducted under axisymmetric (or conventional triaxial) loading (𝜎1>𝜎2=𝜎3).
