Behavior of transversely isotropic shale observed in triaxial tests and Brazilian disc tests
TL;DR: In this paper, three kinds of experiments, namely the conventional triaxial compression test, reducing confining pressure test, and Brazilian test were conducted on a type of shale rock specimen with a horizontal bedding plane and a vertical bedding planes collected from Lushan city, Jiangxi Province, China to further investigate the bedding effect on the mechanical properties of shale rocks.

Investigation on physical and mechanical properties of bedded sandstone after high-temperature exposure
TL;DR: In this article, the effect of exposure to high temperatures on the physical and mechanical properties of bedded sandstone specimens was analyzed. But the results showed that for sandstone with a constant bedding orientation, as the temperature increases, the P wave velocity first increases and then decreases, while the mass and density decrease.

Effect of Grain Size on the Mechanical Behaviour of Granite Under High Temperature and Triaxial Stresses
TL;DR: In this paper, the difference in thermal and mechanical properties between the granite in Luya Mountain, Shanxi Province, China (coarse-grained granite) and the granite from Shandong Province and Gao et al. under high-temperature (100-400 ǫ) triaxial stress was studied.

The influences of heating and uniaxial loading on granite subjected to liquid nitrogen cooling
TL;DR: In this paper, an auxiliary method, heating followed by sharply cooling, is used to reduce the strength of hard rock before mechanical drilling, which can reveal the softening effect of such thermal loading on hard rock.

Quasi-static fault growth and shear fracture energy in granite
TL;DR: In this article, the failure process in a brittle granite sample can be stabilized by controlling axial stress to maintain a constant rate of acoustic emission, and the post-failure stress curve can be followed quasi-statically, extending to hours the fault growth process.

The transition from brittle faulting to cataclastic flow in porous sandstones: Mechanical deformation
TL;DR: In this article, the authors investigated the inelastic and failure behavior of six sandstones with porosities ranging from 15% to 35% and used a broad range of effective pressures to investigate the transition in failure mode from brittle faulting to cataclastic flow.
