DEM simulations of sandstone under true triaxial compressive tests
Acta Geotechnica, 2016Numerically 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 (DEM), in particular the effect of the intermediate principal stress (σ 2 ...

True-triaxial compressive strength of Maha Sarakham salt
International Journal of Rock Mechanics and Mining Sciences, 2013Abstract True triaxial compressive strengths of the Maha Sarakham salt are experimentally determined by using a polyaxial load frame. The salt specimens with nominal dimensions of 5.4×5.4×10.8 cm 3 are loaded to failure with the minimum principal stress, σ 3 , varying from 0 to 7 MPa, and the intermediate principal stress, σ 2 , varying from 0 ...

Behavior of EPS geofoam in true triaxial compression tests
Geotextiles and Geomembranes, 2008Abstract This paper investigates the behavior of EPS geofoam in a true triaxial apparatus using 70 mm×70 mm×140 mm prismatic brick-shaped specimens. The specimens are subjected to different stress paths in the deviator ( π ) plane by means of stress-controlled loading, in which the axial stress is imposed at a rate of 75 kPa/min in the major ...

Damage Evolution and Failure Behavior of Sandstone under True Triaxial Compression
Geotechnical Testing Journal, 2018Abstract In the present study, a series of conventional triaxial tests (CTTs) and true triaxial tests (TTTs) were performed on sandstone through a self-developed true triaxial testing system, which was combined with acoustic emission (AE) monitoring and X-ray computed tomography (CT) scanning technique to systematically study the damage ...
