A review of the tensile strength of rock was conducted to determine the relationship between
direct tensile strength (DTS) and Brazilian tensile strength (BTS) and to examine the validity …

Rock fracture under upper crustal conditions is driven not only by applied stresses, but also
by time-dependent, chemically activated subcritical cracking processes. These subcritical …

Rock mass characterization is required for many applications in rock engineering practice
including excavation design, support design, stope design, amongst others. For these …

The primary objective of this work was an examination of the complimentary roles of tensile
damage and confinement reduction (or stress relaxation) on excavation response of “hard” …

The characterization of time‐dependent brittle rock deformation is fundamental to
understanding the long‐term evolution and dynamics of the Earth's crust. The chemical …

The potential mechanism responsible for water-weakening effects on the direct tensile
failure of rocks remains poorly understood due to the difficulty of experimental control and …

The rock mass around an underground opening is subjected to a unique stress path that
results in low radial confinement and both tangential loading and unloading conditions near …

When the stress-induced risks to a projects warrant it, in situ stress must be measured.
However, as the stress-induced risks increase, ie, the stress magnitudes approach the rock …

Tensile strength is one of the important mechanical properties of rock and rock-like materials
and its accurate estimation and understanding of its failure mechanism are crucial for …

The qualitative description of rock masses by means of classification systems and
subsequent correlation to establish engineering quantities or design parameters has …
