Inelastic compaction and failure mode of Bleurswiller sandstone under true triaxial compression

2023
Previous investigations of the compressive failure of porous rocks under true triaxial compression have focused on the brittle faulting regime. These studies have underscored the dependence of the peak stress state on the interplay of the three principal stresses.

Dynamic compression behaviors of concrete under true triaxial confinement: An experimental technique

Mechanics of Materials, 2020
Abstract A dynamic testing system for concrete-like material under static triaxial confinements is developed in the present article. The cubic specimen with length 50 mm is constrained by six steel square bars. The static triaxial confinements are applied on the specimen through six steel bars that independently servo-controlled by three hydraulic ...

The creep-seepage characteristics of rock under true triaxial compressions

Physics of Fluids
Carbon storage, nuclear waste disposal, tunnels, and other underground engineering have a long service life and require accurate permeability control. The surrounding rock is subjected to a true triaxial stress state because of tectonic stress and engineering disturbance.

Generalized crack damage stress thresholds of hard rocks under true triaxial compression

Acta Geotechnica, 2019
The rock failure process can be characterized by several distinct stress thresholds: the crack closure stress σcc, crack initiation stress σci, crack damage stress σcd and peak stress σp. Seventy-one true triaxial compression tests were conducted to investigate the crack damage stress σcd, which is the stress at the onset of unstable crack development ...

Time-dependent behaviour and modeling of Jinping marble under true triaxial compression

International Journal of Rock Mechanics and Mining Sciences, 2018
Abstract The time-dependent deformation, creep rate, and long-term strength of Jinping marble under different 3-D stress states were studied by using true triaxial creep experiment. A 3-D visco-elastic-plastic creep model, which can describe the accelerated creep， was developed according to the true triaxial time-dependent deformation curve .

Hydraulic Stimulation Experiments in a Decimeter-scale True Triaxial Compressive Apparatus

Geothermal energy is considered a sustainable energy source for the transition to a carbon-neutral economy. In Central Europe, sufficiently hot source rocks are buried deep underground and comprise tight crystalline basement formations. To extract their thermal energy, hydraulic stimulation is used to create efficient heat exchangers in the context of ...
