A true triaxial apparatus (TTA) was designed and fabricated at Northeastern University,
Shenyang, China, by modifying the original Mogi type testing apparatus to emulate three …

We conducted an extensive suite of true triaxial experiments in two porous sandstones,
Bentheim (porosity≈ 24%) and Coconino (17.5%). Our experiments demonstrate that failure …

Abstract The generalized Zhang–Zhu (GZZ) strength criterion has a high associated fitting
accuracy for true triaxial test data. It makes direct use of the parameters of the Hoek–Brown …

Numerically simulated true triaxial compression tests (σ 1≥ σ 2≥ σ 3) are conducted in this
study to elucidate the failure mechanism of sandstone using 3D discrete element method …

We performed an extensive suite of true triaxial experiments in two porous sandstones,
Bentheim (porosity≈ 24%) and Coconino (17%). The experiments were conducted using a …

Brittleness is an important property of rocks in the context of engineering applications, as it
often determines how severe the practical consequences of rock yield will be. Many authors …

We summarize two suites of recent true triaxial tests in two porous sandstones, Coconino
and Bentheim. One suite of tests conducted under constant σ 2 and σ 3, which revealed the …

True triaxial tests (σ 1≥ σ 2≥ σ 3) were conducted on the Zigong sandstone with a relatively
low porosity of~ 6.5% with the aim of assessing the influence of the intermediate principal …

The deformational characteristics of a set of synthetic sandstones when subjected to true
triaxial stress conditions were investigated in this study. The experimental results showed …

The Mogi-type true triaxial apparatus (TTA) for rocks provides numerous advantages in
terms of complexity, loading capacity, permeability measurement, and cost. However, the …
