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 …

Stability and safety of rock structures are easily influenced by the dynamic disturbance,
especially when weak joint planes exist. In order to investigate the filling joint effect on the …

Dynamic impact tests were conducted on rectangular marble specimens with flaws to
investigate the effect of the flaw angles and ligament angles on the rock dynamic …

Many large engineering projects, eg, the Sichuan–Tibet Railway, inevitably cross the
earthquake active areas and the geology complicated zones, facing the challenges of …

In this study, the simultaneous observation of stress wave propagation and crack
propagation was realized through the wave-crack synchronous test, which clarified the …

Dynamic impact tests are performed on prismatic marble specimens containing a single flaw
using a modified split-Hopkinson pressure bar device. The effects of pre-existing flaws with …

The cracks in a rock tend to initiate, propagate, and coalesce under loading. Based on the
digital image correlation (DIC) method, uniaxial compression tests are carried out on rock …

The present work is devoted to the simulation of stress wave propagation through fractured
elastic media, such as rock mass, by using the numerical manifold method (NMM). A single …

Generally, after excavation, a part of the rock slope or underground tunnel surrounding rock
remains in a triaxial extension state. Meanwhile, the natural fissures in the rock mass are …

This paper presents an investigation of wave transmission in complex rock masses; the
rocks have different wave impedances on either side of a joint. The conventional …
