The mechanical characteristics and failure behavior of rocks containing flaws or
discontinuities have received wide attention in the field of rock mechanics. When external …

To comprehensively understand the differences in mechanical behavior of coal during the
mining process at different depths, cyclic triaxial loading and unloading (CTLU) experiments …

Acoustic emission (AE) and particle flow code (PFC3D) are utilized to characterize
microcracking nature in mode-I fracture of coal with strong bursting liability. The microcracks …

Hydraulic fracturing is routinely used, but the fracturing processes that occur when rocks are
hydraulically-fractured are not entirely understood and require further investigation. This …

Acoustic emission (AE) is defined as elastic waves associated with a rapid release of
localized stress energy that is propagated within a material. It has been proven to be a …

We study acoustic emissions (AEs) associated with shear and tensile failures around a
horizontal borehole in a sandstone sample subjected to triaxial stress. The aim is to relate …

The spatial localization of the damage evolution caused by a fiber-reinforced backfill is
critical for the prediction of the rupture location in a mining area filling. Acoustic emission …

We conduct a comparative laboratory investigation of the cracking behaviour of granite,
marble and sandstone using semi-circular bending (SCB) tests on pre-notched specimens …

We performed hydraulic fracturing experiments on cylindrical cores of anisotropic shale
obtained by drilling normal to the sedimentary plane. Experiments were conducted under …

Probing source mechanisms of natural and induced earthquakes is a powerful tool to unveil
associated rupture kinematics. The source processes of failure and slip instability driven by …
