Relation between the sliding friction angle of rock joints and the friction angle of intact cores at the brittle-ductile transition: An experimental study
The sliding friction angle is a fundamental mechanical property both for intact and jointed
rocks. The aim of this paper is to compare the value of sliding friction angle obtained from …

[HTML][HTML] Modeling Brittle-to-Ductile Transitions in Rock Masses: Integrating the Geological Strength Index with the Hoek–Brown Criterion
Many studies focus on brittle–ductile transition stress in intact rocks; however, in real life, we
deal with rock mass which contains many discontinuities. To fill this gap, this research …
