New method for true-triaxial rock testing [PDF]
International Journal of Rock Mechanics and Minings Sciences, 1997 Two new and related true-triaxial apparatus are described that make use of conventional triaxial pressure vessels in combination with specially configured, high-pressure hydraulic jacks inside these vessels. The development combines advantages not found in existing facilities, including a compact design, pore-pressure and flow-through capabilities, the

Aeolian Sand Test with True Triaxial Stress Path Achieved by Pseudo-Triaxial Apparatus
Sustainability, 2023 Aeolian sand is a special roadbed filler, but its three-dimensional mechanical properties are rarely studied. To obtain the characteristic of its deformation, strength on the deviatoric plane, and failure in three dimensions, a series of triaxial drained tests on aeolian sand in the Tengger Desert, under the condition of the constant average principal ...
