Brittle-ductile transition and failure mechanism of Jinping marble under true triaxial compression
Engineering Geology, 2018Abstract The research was focused on the execution of true triaxial compression tests and adopted acoustic emission (AE) and scanning electron microscopy (SEM). By doing so, the authors investigated the strength, deformation, AE, macroscopic and microscopic failure characteristics of Jinping marble in the 3-d stress space during brittle-ductile ...

Experimental Study of Failure Differences in Hard Rock Under True Triaxial Compression
Rock Mechanics and Rock Engineering, 2019In view of a previous study of the intermediate principal stress effect at a limited σ2 range, a series of true triaxial tests, covering a full range of intermediate principal stresses that vary from the generalized triaxial compression stress state (σ2 = σ3) to the generalized triaxial tensile stress state (σ1 = σ2), was carried out on sandstone and ...

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 ...
