In this paper, the shear behaviour and mechanisms of asperity degradation of rock joints
under direct shear tests were studied using numerical and experimental approaches …

A large number of studies have been carried out to investigate the effect of scale on the
shear behaviour of rock joints. However, the nature of scale dependency of rock joints is still …

The joints are existing throughout the underground rock mass. It is of great significance to
investigate the shear performance of the rock mass to maintain the stability of the …

This paper aims to study the shear behaviour of rock joints in a direct shear test using the
particle flow code PFC2D. In this numerical approach, the intact rock is simulated by densely …

The role of surface geometry and its evolution during shearing process on the
hydromechanical behaviour of rock discontinuities has long remained an open question for …

The mechanical performance of fully grouted rock bolts is essential in the stability of
underground excavations in jointed rock masses. This research implements a new cohesive …

The effect of dynamic normal loading (DNL) on the direct shear behavior of a plane joint has
been first time investigated using a dynamic direct shear box device. Multi-stage normal …

A cohesive grain based model is proposed to simulate the fracture behaviour of
polycrystalline rocks. The model was employed to characterize the cracking response of …

Due to the difficulties associated with performing a direct uniaxial tensile test, the tensile
strength of brittle materials is commonly estimated indirectly. The Brazilian test is probably …

Frictional behaviour of joints/faults is of great importance in many geo-engineering
applications across different scales. It is known that the joint surface roughness is one of the …
