Railway ballast anisotropy testing via true triaxial apparatus [PDF]

open access: yesTransportation Geotechnics, 2020
This paper aims to demonstrate the anisotropic behaviour of railway ballast via true-triaxial tests. To do so, a novel, large-scale, true-triaxial testing apparatus (GeoTT) is designed and constructed. It consists of six hydraulic actuators, designed to apply a distributed stress to large granular cubic test specimens with dimensions: 500 mm × 500 m ...

New method for true-triaxial rock testing [PDF]

open access: yesInternational Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 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

Strength and deformation properties of frozen sand under a true triaxial stress condition

open access: yesSoils and Foundations, 2022
In recent years, the mechanical properties of frozen soils under complex stress states have attracted significant attention; however, limited by the test apparatus, true triaxial tests on frozen soils have rarely been conducted. To study the strength and

A study on the influences of a hygrothermal environment on the compressive strength and failure criteria of asphalt mixtures based on true triaxial tests

open access: yesHeliyon, 2022
Based on a high-pressure servo static and dynamic true triaxial test machine (tawz-500/300), uniaxial and true triaxial tests of AC-25C asphalt mixtures under different heat moisture coupling treatments were performed, and the triaxial compressive ...

Aeolian Sand Test with True Triaxial Stress Path Achieved by Pseudo-Triaxial Apparatus

open access: yesSustainability, 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 ...

An MCMC Fitting Method for Triaxial Dark Matter Haloes [PDF]

open access: yes, 2008
Measuring the 3D distribution of mass on galaxy cluster scales is a crucial test of the LCDM model, providing constraints on the behaviour of dark matter. Recent work investigating mass distributions of individual galaxy clusters (e.g.
