Prediction of the rockburst proneness of rock in the field is an important problem in rockburst
research. In this paper, the analytical relationship between the strength ratio (the ratio of the …

A series of uniaxial and triaxial compression tests were performed on slate samples with
different diameters at different foliation orientations with respect to the direction of the major …

In this paper, a number of artificial rock specimens with two parallel (stepped and coplanar)
non-persistent joints were subjected to direct shearing. The effects of bridge length (L) …

In this study, a new calibration procedure was proposed to calibrate the micro-parameters
for the flat-joint model. Both uniaxial compression and Brazilian test simulations were …

The constant mi is a fundamental parameter required in the Hoek–Brown (H–B) failure
criterion for estimating rock strength. Triaxial tests for the calculation of this constant are time …

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 …

Characterising the size-dependent behaviour of rock has been a significant challenge in
rock engineering particularly during the design of structures on or within a rock mass …

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 …

When carrying out compressive tests on rock specimens, a stress plateau is typically
attained following peak strength within a strain range a few times larger than the strain at …

Compression testing schemes that induce failure in rock specimens primarily through a
reduction in confining stress have become increasingly common in recent years. Despite …
