The purpose of this review is to discuss the development and the state of the art in dynamic
testing techniques and dynamic mechanical behaviour of rock materials. The review begins …

Filled inclusions in rock discontinuities play a key role in the mechanical characteristics of
the rock and thereby influence the stability of rock engineering. In this study, a series 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 carried out on red sandstone specimens with single bonded
planar joint at various angles based on a split Hopkinson pressure bar (SHPB), to …

The instability of shotcreted structures, eg, the underground tunnels after shotcreting, often
results from the tensile failure of the rock-concrete interface. However, the understanding of …

Research on rock fracture behavior is usually limited to static mixed mode I/II fracture and
static or dynamic mode I fracture. In this study, the notched semi-circular bend (NSCB) …

The tensile strength of rock is a crucial parameter for the stability assessment and
reinforcement design of rock engineering, which is commonly determined by indirect tension …

The present study essentially employs a thin-layer interface model for filled rock joints to
analyze wave propagation across the jointed rock masses. The thin-layer interface model …

Abstract Based on the Split Hopkinson Pressure Bar (SHPB) device, a new combined
compression and shear loading technique is developed by adding cushions with designed …

Jointed rock masses of roadways in underground coal mines are heavily disturbed by rock-
cutting vibrations from Tunnel Boring Machines (TBMs), posing significant challenges in …
