This article reviews the effect of weak interfaces on crack propagation in rock and some
other analogous brittle materials from phenomenon to mechanism. In this review, a variety of …

Mineral grains serve as the basic units of rocks. Understanding rock materials at the grain-
scale level allows us to unveil the underlying fundamental mechanisms, thereby facilitating …

Rock masses in high-elevation or cold areas are vulnerable to the joint results of freeze-
thaw (FT) action and dynamic loading, it is thus significant to evaluate the tensile mechanical …

The influence of the loading rate on the mode I fracture property of rocks has been
extensively investigated through experiments. However, the rate-effect of the dynamic mode …

A series of mode I fracture tests under coupled static-dynamic loading were performed on
notched semi-circular bend (NSCB) sandstone specimens using the split Hopkinson …

Determination on underlying mechanisms of crack initiation is of vital importance to
understand the failure processes of geomaterials in practical engineering. In this study …

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 …

In this study, a series of uniaxial compression and acoustic emission (AE) tests were
conducted on sandstone specimens immersed in water for different durations (0–720 h). The …

Underground mined-out areas and tailings are the two major harmful consequences from
metal mining industry. Cemented Paste Backfill (CPB) method, refilling the tailings back to …

Rocks in deep underground engineering are prone to encounter pre-static loads and
dynamic disturbances simultaneously. Meanwhile, pure mode I and mixed mode I–II …
