The textural characteristics of rocks influence their petrophysical and mechanical properties.
Such parameters largely control rock mass stability. The ability to evaluate both immediate …

Multistage constant-amplitude-cyclic (MCAC) loading experiments were conducted on Tibet
interbedded skarn to investigate and characterize fatigue mechanical behavior of the tested …

After the excavation of deep underground engineering, the complex 3D high-stress
redistribution occurs in the surrounding rock, resulting in deterioration of mechanical …

Rock macro-indentation plays a fundamental role in mechanical rock breaking for various
rock engineering application, such as drilling, tunneling, cutting, and sawing. Over the past …

Six different sandstones were studied to investigate and quantify the effects of heating and
cooling, wetting and drying, and freezing and thawing (climatic changes) on their unconfined …

Conclusions The work presented here was undertaken to investigate the effects of loading
amplitude and frequency on strength and deformation behaviour of rock in uniaxial …

Mineral grain size caused by the geological diagenetic process is one of the fundamental
reasons leading to the differences in rock mechanical behaviors, which brings challenges to …

Damage evolution salt rock under fatigue loading at different stress amplitudes, loading
frequencies, and loading rates was investigated in the laboratory. Under conditions of …

Lower Paleozoic shale is an important hydrocarbon source rock and natural gas reservoir in
the Upper Yangtze Plate. In this study, compressive strength+ acoustic emission (AE), low …

To better understand how textural properties and mineralogy control compressive strength,
this work performed the grain size analysis, porosity measurement, X-ray diffraction …
